I explain that Muslims DO NOT have a holy atonement for their sin. Therefore cannot be in the presence of God. God is just, therefore requires punishment for sin, and ones actions through the tawbah, is not enough to satisfy god's judgement for sin. It must be holy and justified. As Paul says in Galatians 2 v15-21. We are not justified by our works, but by faith in Jesus Christ and his actions on the cross. All pagan god's alongside Islam are going to hell, because they don't have a holy atonement.
