And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life. – 1 John 5:20 ESV
1 John 5:13-21
John closes his letter with a strong note of affirmation: “We know that the Son of God has come.” John has given his own personal testimony to that fact, along with the testimonies of the three very reliable witnesses, not to mention God Himself. The evidence is more than sufficient to prove that Jesus not only came, but that He was and is the Son of God. He existed before the creation of the world with God. Not only that, He played a major part in the creation of the world. John begins his gospel with these words: “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made” (John 1:1-3 ESV). The deity of Jesus is essential to the plan of salvation. Without it, mankind’s sin problem remains unchanged. We are left with the ever-present reality of sin in our lives and the complete incapacity to refrain from sin or remove the guilt and sentence of death associated with it. There were those in John’s day who believed that Jesus simply came to show us a better way to live. He came to give us a more enlightened moral code by which to conduct our lives. But Jesus’ entire life led to the cross, where He sacrificed Himself for the sins of mankind. He atoned for man’s sin by offering Himself as a worthy, sinless sacrifice. And as a result, when anyone places their faith in Him as their Savior and sin substitute, they receive not only cleansing from sin, but His righteousness. In other words, Jesus didn’t just pay our debt off and bring our balance to zero. That would still have left us spiritually penniless and helpless. No, what Jesus did was give us His righteousness. He replaced our indebtedness to God with the wealth of His righteousness. “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Corinthians 5:21 ESV). Not only that, He provided a way for us to know God and experience fellowship with Him for the very first time in our lives.
We can know the one, true God. No longer are we left to try and conjure up our own version of God or find something else that might act as a stand-in for Him. Because of Jesus’ death on the cross, we can actually, legitimately know God. We can come into His presence. And when we do, we come as His children, not groveling, fearful debtors. He looks on us as His own children. He sees us as righteous, because our sins have all been paid for in full – past, present and future. We no longer have to try and earn His favor. We don’t have to attempt to measure up and keep our sin-quotient below 50 percent. Yes, we are to live holy lives, because that is what He has called us to. But we don’t do it out of a sense of obligation or in order to earn His love and favor. We do it gladly, out of love for Him. And we do it in the strength He has provided us through His indwelling Holy Spirit. Our testimony can be that of Paul’s, “It is no longer I who live, but Christ lives in me. So I live in this earthly body by trusting in the Son of God, who loved me and gave himself for me” (Galatians 2:20 ESV). Through the Holy Spirit, Christ lives in us. The Spirit of God has taken up a permanent residence within each and every believer.
But the main point John leaves us with as he closes out his letter is that “we may know him who is true.” By coming to know Jesus as Savior, we come to know God the Father. There is no other way. Any other attempt to come to know God will fall short. It will end in idolatry, a false form of God. Rather than the true God, man will always end up worshiping false gods – apart from Christ. John wants us to know that Jesus makes it possible for us to know the one true God and experience eternal life. But one of the false perceptions among many believers is that eternal life is somehow a commodity. It is some kind of future reward reserved for those who make the right choice and place their faith in Jesus. But Jesus said, “this is eternal life, that they know you the only true God, and Jesus Christ whom you have sent” (John 17:3 ESV). Knowing God and Jesus is eternal life. It is the reward. A relationship with God and His Son is the prize. But do we value it? Do we fully appreciate the remarkable reality that we can have an intimate, experiential knowledge of God – right here, right now? Jesus has made it possible for us to know and understand the infinite, indefinable, all-powerful God of the universe. Through the living word, Jesus; and the written Word, the Scriptures; and the indwelling Spirit; we can know and understand God. We can come to comprehend His character and nature. We can grow in our knowledge of Him. We can increasingly see His incredible love for us and respond in kind. Rather than seeing Him as distant, detached and difficult to understand, we can know and love Him. And we don’t have to wait for heaven in order to start. What an incredible privilege.
