Adulterers and adulteresses! Do you not know that friendship with the world is enmity with God? Whoever therefore wants to be a friend of the world makes himself an enemy of God (James 4:4).
Unfaithful to God is one who is a friend of the world. “The righteous should choose his friends carefully, for the way of the wicked leads them astray” (Prov 12:26 NKJ). The world is full of wicked people who have no regard for God. “The wicked in his proud countenance does not seek God; God is in none of his thoughts” (Ps 10:4). We should not be friends with such people. They will lead us away from God just like the idols of heathen nations led Israel away from God and just like the idols of Solomon’s wives led him away from God. “Remove your way far from her, and do not go near the door of her house” (Prov 5:8). The world is like kudzu. It will wrap itself around you unless you beat it back. “For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and overcome, the latter end is worse for them than the beginning” (2 Pet 2:20). Deny ungodliness and worldly lusts (Titus 2:12).
