God want you to forgive them, but he didn't say you should mingle with them. God want you to love them brotherly with Agape love, but he didn't say you should befriend them or associate with them. Be not unequally yoked with unbelievers. Come out from among them and be separate. If they misled you once they can do it again, If they hurt you once they can hurt you again. Be wise as a serpent and harmless like a dove.
