“If Bruce has received Jesus Christ, he’s a Christian.”
You cannot “receive Jesus Christ” and deny God’s Word. Jesus told people to go and sin no more, not to rejoice in their sins and promote sin to others.
Jesus does not “accept” us. If He did, we would have no reason to change. God hates sin. God will punish sin. Until someone knows that, they have no reason to ask for forgiveness. You cannot be a “believer” while denying what God has revealed.
Of course God hates sin and the demonstration of how much He hates sin is his exacting the full punishment and condemnation for every sin of every person on the body of his beloved Son. IT IS FINISHED.
