By This We Know.

By his we know that we abide in him and he in us, because he has given us his Spirit. – 1 John 4:13 ESV

How do you know that you’re truly saved? What gives you the rock-solid assurance that you have placed your faith in Christ and that God has accepted you as His child? John gives us one, very reliable proof: The presence of the Holy Spirit within us. “And God has given us his Spirit as proof that we live in him and he in us” (The New Living Translation). John had already talked about this matter once before back in chapter three. “Those who obey God’s commandments remain in fellowship with him, and he with them. And we know he lives in us because the Spirit he gave us lives in us” (1 John 3:24 NLT). Our very ability to obey God’s commands is due to the presence of the Spirit of God within us. We would be unable to live obediently without Him. When we sinned, we would experience no conviction without His help. It is the Holy Spirit who provides us with the assurance of our salvation. Paul described Him as a kind of down-payment or guarantee of things to come. “It is God who enables us, along with you, to stand firm for Christ. He has commissioned us, and he has identified us as his own by placing the Holy Spirit in our hearts as the first installment that guarantees everything he has promised us” (2 Corinthians 1:21-22 NLT). This was a favorite theme of Paul’s. He said the very same thing to the church in Ephesus. “The Spirit is God’s guarantee that he will give us the inheritance he promised and that he has purchased us to be his own people. He did this so we would praise and glorify him” (Ephesians 1:14 NLT). In his letter to the believers in Rome, he added a slightly different twist: “The Spirit himself bears witness with our spirit that we are children of God” (Romans 8:16 ESV).

By THIS we know. It is the Holy Spirit within us who should provide us with an overwhelming since of peace and confidence that we belong to God. The very fact that He lives in us and is constantly attempting to guide, convict, comfort, and transform us, should let us know that God is in us and we are in God. The Holy Spirit provides us with the ability to understand the truths of God. Paul told the believers in Corinth, “we speak words given to us by the Spirit, using the Spirit’s words to explain spiritual truths” (1 Corinthians 2:13 NLT). Then he went on to explain the sad, but true facts concerning those who don’t have the Spirit of God within them. “But people who aren’t spiritual can’t receive these truths from God’s Spirit. It all sounds foolish to them and they can’t understand it, for only those who are spiritual can understand what the Spirit means” (1 Corinthians 2:14 NLT). Concerning the Holy Spirit, Jesus told His disciples, “The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you” (John 14:17 NET). He promised His followers that the Holy Spirit would take up residence within them. And His indwelling presence would make it possible for them to understand the words of Christ in ways they never could have before.

The Spirit provides us with assurance that we are in Christ. He lets us know that we are God’s children. But it is possible to live as if He does not exist. We can treat Him as if He is not there. When we sin, we grieve Him, because we are refusing to rely upon His strength and listen to His voice in our lives. When we attempt to live the Christian life in our own strength, we quench Him. We effectively tell Him we don’t need Him. And when we do, we lose all sense of assurance. We begin to doubt. We wonder why we don’t seem to see any transformation in our lives. Paul saw the believers in Corinth doing the very same thing and told them, “Dear brothers and sisters, when I was with you I couldn’t talk to you as I would to spiritual people. I had to talk as though you belonged to this world or as though you were infants in the Christian life” (1 Corinthians 3:1 NLT). They were not acting like Spiritual people. Yes, they had the Spirit of God within them, but they were not allowing Him to do what God had sent Him to do. They were resisting Him. They were ignoring Him. And they were living their lives as if He didn’t even exist. Their lives looked more like those who who are lost and lack the Spirit altogether. Not exactly a rousing endorsement from the apostle Paul.

One of the ways we can tell if someone belongs to God is how they respond to the truth of God as found in the Word of God. When it is preached, they respond favorably. The Spirit within them either convicts or comforts them. John said that his teachings came from God and those who had the Spirit of God living in them were able to hear his words with spiritual ears. “But we belong to God, and those who know God listen to us. If they do not belong to God, they do not listen to us. That is how we know if someone has the Spirit of truth or the spirit of deception” (1 John 4:6 NLT). Spiritual people, those who have the Spirit of God living in them, are able to accept spiritual truth. It makes sense to them. They may not always accept it or obey it, but they get it. They have a choice to listen to it and allow the Holy Spirit to use it to transform their lives, or they can simply choose to act as if they never heard it. But they know what they heard. They know what the Spirit has said. So even in our disobedience we know that He is there. And that too, should give us assurance. Conviction should be comforting. It should remind us that God is there, in the form of His Spirit. By this we know that we are His children, because He has placed His Spirit within us, to comfort, convict, guide, empower, help and teach us.

Walk the Talk.

Little children, let us not love in word or talk but in deed and in truth. – 1 John 3:18 ESV

Life change. That’s really a big part of what John seems to be stressing in his letter. What we believe should impact how we behave. Who we are (children of God) should significantly alter what we do. And John focuses on one specific outcome of our relationship with Christ: our love for one another. After all, the world goes out of its way to hate us, just as it hated Jesus. But we are to love one another. We have passed from life to death, from being dead in our trespasses and sins (Ephesians 2:1) to new life in Christ (Ephesians 2:5). If we fail to love, it is as if we are still dead, exhibiting the characteristics of our former spiritual lifelessness. The dead don’t love. The dead can’t love. But we are alive in Christ because “he laid down his life for us” (1 John 3:16 ESV). And as a result of that life-giving, new-creation kind of love, we have the capacity to love others – even to the point of laying down our lives for them just as Jesus laid down His life for us. Christ’s love for us was tangible and visible. He gave His life. He laid it all on the line. So for us to claim to love one another, we will have to give proof of that love in tangible, visible ways. John says, “if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him?” (1 John 3:17 ESV). In other words, how can you claim to have the love of God abiding in you if you can’t seem to express love to someone else whose need could be met by your surplus? James points out the absurdity of that kind of lifestyle when he writes, “If a brother or sister is poorly clothed and lacking in daily food, and one of you says to them, ‘Go in peace, be warmed and filled,’ without giving them the things needed for the body, what good is that?” (James 2:15-16 ESV). The old saying, “talk is cheap” is so true. Words that aren’t backed up by action are meaningless. John gives us two pairs of words. He says, we are not to love in word or talk. The word for “talk” can actually be translated “tongue”, as in the muscle inside our mouth. It is out tongue that produces words. In the same way, it is truth that produces deeds. The truth concerning Jesus and His transforming power in our lives shows up as actions that reflect our new nature. We are able to love others because we have been loved by Him.

John reminds us that our belief in the name of Jesus, as the Son of God and our Savior from sin, coupled with our love for one another provide evidence of our relationship with God. We abide in Him and He abides in us. It is His Spirit within us that enables us to walk the talk. He helps us turn truth into action, and we get to see the love of God perfected or completed (1 John 2:5). As the Spirit enables us to love our brothers and sisters in Christ, it reflects God’s love flowing to us and through us to others. It doesn’t dead end with us, but continues on to others as we act as conduits through whom His love flows.

But the love we are to share is far more than some kind of emotional or sentimental feeling. It is not to be self-seeking or reciprocal in nature, demanding payback or expecting love in return. The kind of love we are called to show others is radical and not like anything this world has ever seen. Paul describes it this way: “

Love never gives up.
Love cares more for others than for self.
Love doesn’t want what it doesn’t have.
Love doesn’t strut,
Doesn’t have a swelled head,
Doesn’t force itself on others,
Isn’t always “me first,”
Doesn’t fly off the handle,
Doesn’t keep score of the sins of others,
Doesn’t revel when others grovel,
Takes pleasure in the flowering of truth,
Puts up with anything,
Trusts God always,
Always looks for the best,
Never looks back,
But keeps going to the end.

– 1 Corinthians 13:4-7 NLT

We are to love in the same way that He loved us. And when we do, others will see it and know that we are His disciples. Why? Because that kind of love can’t be faked. It isn’t natural or normal. It’s not of this world. It comes from a different source. It’s full of life, not death. It builds up, instead of tearing down. It it other-focused rather than me-centered. It’s measurable, meaningful, tangible, helpful, and incredibly hopeful. When we walk the talk and love as He loved, we can know that He lives within us and He is in the process of transforming us, through His power and in His timing.

By This We Know.

And by this we know that we have come to know him, if we keep his commandments. – 1 John 2:3

Profession of a having a relationship with God cries for proof. It begs for evidence. Following up with his assessment of false claims of intimacy with God found in the previous verses, John says, “Whoever says ‘I know him’ but does not keep his commandments is a liar, and the truth is not in him” (1 John 2:4 ESV). That sounds eerily similar to what John wrote just a few verses earlier. “If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth” (1 John 1:6 ESV). From John’s perspective, the assertion of intimacy with God means nothing without the kind of behavior that gives evidence that one is truly walking in the light. Obedience to the commands of God is proof that one has a relationship with Him through His Son, Jesus Christ the righteous. His light has illuminated the darkness of our lives, exposing the sin within, and replacing it with the power to live holy lives, set apart for His glory. To claim to have an abiding, ongoing, personal and intimate relationship with God through Christ is one thing. To live like it is another. “Whoever says he abides in him ought to walk in the same way in which he walked” (1 John 2:6 ESV). That is a serious and sobering statement. It is a call to a radical, revolutionary kind of lifestyle that looks nothing like what we see modeled on this earth.

Jesus came to dispel darkness. He came to penetrate the darkness of man’s sin with the light of His life. He said of Himself, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life” (John 8:12 ESV). But it does no good to claim to know the light of the world if our lives do not reflect the presence of that light on a daily basis and in practical ways. The apostle Paul puts this in terms we can understand and apply. “For God, who said, ‘Let there be light in the darkness,’ has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ. We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves” (2 Corinthians 4:6-7 NLT). The light of God in the form of His Son, Jesus Christ, has penetrated the darkness of our lives and the result should be that it shine OUT of our lives in ways that prove its existence. John tells us what that should look like on a daily basis. And he ties it back to the greatest commandment as Jesus explained it. “You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself” (Matthew 22:36-39 ESV). Love God and love others. You can’t do one without the other. Without God’s help, loving others is impossible. At least, to love them on God’s terms is impossible. But it is impossible to say you love God if you can’t bring yourself to love those who are supposed to be your brothers and sisters in Christ. Supposedly the darkness of our lives has been penetrated by the light of Christ. But “whoever says he is in the light and hates his brother is still in darkness” (1 John 2:9 ESV). In other words, their behavior does not reflect their so-called relationship with Christ. If anything it contradicts the truth as expressed by Christ Himself. He said, “If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life” (John 8:12 NLT).

To continue to walk (conduct your life) in the dark when you have been exposed to the Light makes no sense. Anyone whose life is marked by hatred rather than love for his brother, is stumbling around in the dark, “because the darkness has blinded his eyes” (1 John 2:11 ESV). But John says, we can know that we have come to know Christ. We can know we have a relationship with God. We can know that we are in him. And the proof is in the transforming power of Christ in us. We can love others. And when we love others we are expressing and proving our love for God. We are giving evidence of His Spirit’s presence within us. We are walking (living our lives) in the same way Jesus did. In obedience and dependence upon God. Claiming to know Him is one thing. Living as if we know Him is another. And the strength to accomplish is God-provided, not self-made. “By his divine power, God has given us everything we need for living a godly life” (2 Peter 1:3 NLT). Life transformation is evidence of our ongoing sanctification by God. By this we know.
