¹⁵ Look carefully then how you walk, not as unwise but as wise, ¹⁶ making the best use of the time, because the days are evil. ¹⁷ Therefore do not be foolish, but understand what the will of the Lord is. ¹⁸ And do not get drunk with wine, for that is debauchery, but be filled with the Spirit, ¹⁹ addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart, ²⁰ giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ, ²¹ submitting to one another out of reverence for Christ. – Ephesians 5:15-21 ESV

Once again, Paul brings up the issue of the believer’s walk or how they conduct their life. He has already told his readers “to walk in a manner worthy of the calling to which you have been called” (Ephesians 4:1 ESV). He has warned them, “You must longer walk as the Gentiles do, in the futility of their minds” (Ephesians 4:17 ESV). In verse one of this chapter, he wrote, “walk in love, as Christ loved us and gave himself up for us” (Ephesians 5:1 ESV). And then he gave his readers yet one more admonition: “Walk as children of the light (for the fruit of the light is found in all that is good and right and true)” (Ephesians 5:8-9 ESV).

Now, in verse 15, he provides yet one more word about the daily conduct of believers.

Look carefully then how you walk, not as unwise but as wise, making the best use of the time. – Ephesians 5:15 ESV

Paul had a strong conviction that a believer’s belief and behavior were to be inseparable. Faith in Christ was to have a direct impact on every area of life, including the believer’s attitudes and actions. A Christian’s walk and words were to reflect his new nature. But it is interesting to note that the verses above are all imperatives.

Walk in a manner worthy of the calling.

Walk not as the Gentiles do.

Walk in love.

Walk as children of the light.

Walk not as the unwise.

These are commands, not suggestions, and they require forethought and proper consideration. If you want them to be part of your life, you must think about them and plan for them. Like all the commands in Scripture, they are non-optional, yet not always obeyed. We can choose to ignore each of these commands. That is why Paul was so emphatic. He begged his readers not to act thoughtlessly, and he put it in very blunt terms: “Do not be foolish” (Ephesians 5:17 ESV).

To “be foolish” was to act without reason or reflection; to act rashly, without forethought or proper consideration. Living the Christian life requires a bit of brainpower and intellectual capacity. We have to think about what we are doing, and that requires planning and deliberation. In verse 10, Paul wrote, “Carefully determine what pleases the Lord” (Ephesians 5:10 NLT). That requires thought and consideration. You must stop and consider the deed before you commit to doing it. In his letter to the believers in Rome, Paul provided them with a key to making this happen.

Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect. – Romans 12:2 NLT

God wants to redeem our thought lives so that we think as He does. But that requires knowing His will or what He would have us do. Which is why Paul said, “Don’t act thoughtlessly, but understand what the Lord wants you to do” (Ephesians 5:17 NLT). And just in case his readers couldn’t follow his train of thought, Paul gave them a real-life example.

Don’t be drunk with wine, because that will ruin your life. – Ephesians 5:18a NLT

Think about it; what good ever comes from getting drunk? Who has ever been proud of their behavior after a night of heavy drinking? Paul suggests that it would be wiser and more beneficial to “be filled with the Spirit” (Ephesians 5:18b NLT). It should be obvious that when Paul compares being drunk with wine with being filled with the Spirit, he is talking about control. When one is inebriated, they are under the control of alcohol because it determines their behavior. It causes them to do and say things that are out of character.

To be filled with the Spirit is to choose to let Him dictate and determine your behavior. There is a big difference between being indwelt by the Spirit and filled by the Spirit. Every believer receives the Holy Spirit at the point of salvation. But while we have all of the Spirit all of the time, we are not always “filled” or controlled by the Spirit. We can choose to ignore Him. We can determine to disobey Him. But when we are filled with the Holy Spirit and under His control, our behavior will give evidence. Paul provides a glimpse of what that should look like.

Instead, be filled with the Holy Spirit, singing psalms and hymns and spiritual songs among yourselves, and making music to the Lord in your hearts. And give thanks for everything to God the Father in the name of our Lord Jesus Christ. – Ephesians 5:18-20 NLT

Earlier, Paul warned, “Do not grieve the Holy Spirit of God” (Ephesians 4:30 ESV). We grieve the Spirit when we choose to live our lives apart from His power and without His guidance. When we do so, we rob Him of His primary role in our lives. He exists to assist us as we navigate this fallen world, but when we refuse to live under His control, we deny Him the joy of producing His fruit through us. We end up quenching His fruit-bearing power and produce “bitterness and wrath and anger and clamor and slander” instead (Ephesians 4:31 ESV). The Spirit longs to make us kind, tenderhearted, forgiving, thankful, and submissive to one another, but He will not force His will on us. It is a choice we must make. That is why Paul says, “Be filled with the Holy Spirit” (Ephesians 5:18 NLT).

It is God’s will that we be filled. That is the whole reason He provided the Holy Spirit in the first place. In his letter to the Thessalonians, Paul wrote, “For this is God’s will: that you become holy” (1 Thessalonians 4:4 NET). But holiness is unachievable without the assistance of the Holy Spirit. Forgiveness of sins is great, but even an absence of sin does not make someone righteous or holy. God’s intention is to transform us from unrighteous to righteous, from unholy to holy. His ultimate goal is our glorification, when we will be set free from all sin and made perfectly righteous.

It is essential that we stop and consider what God is doing in our lives. We must constantly question why we would choose to do anything that is contrary to His will for our lives. He desires for us to be holy, so why would we do anything that prevents that from happening? That is why Paul tells us, “Don’t act thoughtlessly, but understand what the Lord wants you to do” (Ephesians 5:17 NLT). We must think before we act.

Father, sometimes I fail to think about what You are doing in my life. It is so easy to take my salvation for granted and rest on the promise of my forgiveness and the hope of eternal life. But You are in the transformation business and Your Spirit is constantly working on my life so that my Christlikeness increases with each passing day. But this is a process I must willfully choose to participate in. That means I must think about it and actively pursue those things that please You, instead of me. You have said that we are to be holy as You are holy. That is a call for us to live set-apart lives that reflect Your character and differentiate us from the rest of the world. But again, that is not something that comes naturally, even after salvation. Without the Spirit’s help, I will always gravitate to my old sinful habits. I will do what pleases me and model my life after this world. But thank You for providing the Holy Spirit who never leaves me and never gives up on me. Without Him, my pursuit of holiness would be hopeless. But with His help, I am becoming more like Christ. Amen
