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, 10 who died for us, that whether we wake or sleep, we should live together with Him. 11 Therefore comfort each other and edify one another, just as you also are doing. (1 Thessalonians 5:8–11, NKJV)
Paul returns to soberness as he exhorts Christians (sons of light, sons of the day) to live so as to seize and preserve the salvation to which we have been appointed. It is necessary to protect ourselves from sin with faith, love and hope as we live for Him who died for us. Wrath is appointed for those who indulge themselves in the darkness of sin, choosing to reject the richness of God’s salvation for the futility of the flesh. Christians prepare for Christ’s return by living soberly. We are strengthened and comforted by the assurance of the eternal salvation to be obtained when Christ returns (2 Thess. 2:14; Heb. 10:39; 1 Pet. 1:6-9). You will never find comfort in the darkness of sin. Come out of your sin and live for Jesus. When He returns, Christians will live together with Him forevermore. If you are a faithful Christian, whether you are alive or dead on that day will make no difference. The difference will be whether you lived soberly in the light of truth and obtain salvation, or in the darkness of sin and obtain wrath.
