Ephesians 5:8 - Live as children of light

For you were once darkness, but now you are light in the Lord. Live as children of light

For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:

for you were formerly darkness, but now you are Light in the Lord; walk as children of Light

Ephesians 5:8

Commentary

The believer's position has changed from darkness (sin) to light (righteousness). Believers are to change their walk to correspond to their position in Christ (Rom 12:2).

Darkness / Light

"Darkness" describes the character of the life of the unconverted as void of truth and virtue in intellectual and moral matters (cf. 1 John 1:5-7). The realm of darkness is presided over by the "power of darkness," (Luke 22:53; Col. 1:13) who rules those headed for "eternal darkness" (Matt. 8:12; 2 Pet. 2:17). Tragically, sinners love the darkness (John 3:19-21). It is that very darkness from which salvation in Christ delivers sinners (see notes on John 8:12; Col. 1:13; 1 Pet. 2:9; cf. Ps. 27:1).
