Admittedly, anyone can come to Christ for salvation. A church should welcome sinners, and accept repentant sinners into membership. However, if a person is in a business that promotes sin (adultery, consuming life-altering drugs, etc.) Should the church refuse to offer fellowship to this person? Shouldn't the person get out of the sinful business? Wouldn't his continuing association with the sinful lifestyle have the effect of corrupting the church's membership? (I Cor.15:33)
James 4:4
NKJV - 4 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.
