Romans 2:19
2:19 and if you are convinced 1 that you yourself are a guide to the blind, a light to those who are in darkness,
Romans 13:12
13:12 The night has advanced toward dawn; the day is near. So then we must lay aside the works of darkness, and put on the weapons of light.
1 tn This verb is parallel to the verbs in vv. 17-18a, so it shares the conditional meaning even though the word “if” is not repeated.
