4 But you, brethren, are not in darkness, so that this Day should overtake you as a thief. 5 You are all sons of light and sons of the day. We are not of the night nor of darkness. 6 Therefore let us not sleep, as others do, but let us watch and be sober. 7 For those who sleep, sleep at night, and those who get drunk are drunk at night. 8 But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. 9 For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, (1 Thessalonians 5:4–9, NKJV)
Christians (children of God) are children of the day. Therefore, we are to live watchfully and soberly in the light of truth. The contrast to the inebriation of darkness is easy to understand. Being “of the day” (v. 8) means living soberly in faith, love, and the hope of salvation we have in Jesus Christ. Yet, more and more Christians are partaking in the less than sober practice of drinking intoxicants. Defending “social drinking” of intoxicating beverages as a Christian’s liberty embraces the very thing Paul used to warn us against losing our spiritual alertness. Rather than justify the incremental loss of self-control and the corresponding loss of sharpness, we must refuse even the beginning of this activity associated with darkness (Eph. 5:18; 1 Pet. 4:3).
I thank God, whom I serve with a pure conscience, as my forefathers did, as without ceasing I remember you in my prayers night and day, (2 Timothy 1:3, NKJV)
The conscience distinguishes us from birds, beasts, and fish. They operate on instinct to survive. Humans have been created in the image of God, unlike animals, and the conscience is one such distinguishing trait (Gen. 1:27). The conscience is a moral monitor of what we accept to be right and wrong, but not necessarily of what is right in God’s sight. It is not the standard of right and wrong – God’s word is. (Jiminy Cricket was wrong when he told Pinocchio to “always let your conscience be your guide.”) We can believe and act incorrectly, and yet our conscience can commend us in the error (Acts 23:1; 26:9). The conscience is like an early warning system, monitoring our choices and conduct to help us avoid moral danger. But, we have to train it with God’s truth for it to operate accurately. Just like sensors are adjusted and cleaned so they alert us of danger, our conscience must be “set” (educated) with God’s word and kept pure to accurately warn us of moral threats (see 1 Tim. 4:1-3). God cannot be served when our conscience is defiled by sin and error (Tit. 1:15). Jesus died to cleanse our consciences from “dead works to serve the living God” (Heb. 9:14). It is up to us to educate and train our conscience with God’s word, and to keep it pure by serving God according to His truth.
