1 Corinthians 5:9-10

Galatians 5:19-21

5:19 Now the works of the flesh are obvious: sexual immorality, impurity, depravity, 5:20 idolatry, sorcery, hostilities, strife, jealousy, outbursts of anger, selfish rivalries, dissensions, factions, 5:21 envying, murder, drunkenness, carousing, and similar things. I am warning you, as I had warned you before: Those who practice such things will not inherit the kingdom of God!

Ephesians 5:5-6

5:5 For you can be confident of this one thing: that no person who is immoral, impure, or greedy (such a person is an idolater) has any inheritance in the kingdom of Christ and God.

Live in the Light
