Romans 13 v 12

Romans 13:12
The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.


Paul considered the time of Christ’s return and the consummation of salvation for believers (v. 11) as the start of a new day. The present time, while Christ is absent (John 14:2-3; Acts 1:11) and Satan is at work (2 Cor. 4:4; Eph. 2:2), is described as the night (cf. 2 Peter 1:19). Since “the day” is almost here, Paul urged his readers to put aside the deeds of darkness and put on the armor of light. Christians are soldiers in a conflict who need to be alert and equipped for battle (Eph. 6:10-17; 1 Thes. 5:8). Upright, Christ-honoring living is often referred to as being in the light (John 12:36; Eph. 5:8, 14; Col. 1:12; 1 Thes. 5:5; 1 John 1:7; 2:10).
