God is a God of law and judgment. Everything that God does is according to his law. He will not and cannot overlook sin, which is a transgression of his law, 1 John 3:4. God does not look the other way when it comes to sin.
Many religions are not according to God's law. Calvinism is one of them. Calvinist believe that God has chosen "some certain persons" to be saved, without being justified by the doing and the dying of Jesus, who is God's justifier, Romans 3:26. Jesus only justifies those that believe in him.
"But to him that does no works, BUT BELIEVES ON HIM that justifies the ungodly, his faith is counted for righteousness" Romans 4:5.
The condition for justification is that you believe in Jesus. Not that you have been predestinated. No justification means no salvation. Another religion that is not according to God's law is Catholicism. Catholics believe that they are justified by their works and their piety. There is a serious problem with this. The problem is that everyone is a sinner. God does not accept the works, obedience or the piety of sinners. Catholics believe that God is the minister of sin.
The reason that Jesus is not present on this earth is because of sin. He is here only in the presence of the Holy Spirit.
"For such a high priest became us, who is holy, harmless, undefiled, SEPARATE FROM SINNERS and made higher than the heavens, Hebrews 7:26.
Jesus is not the minister of sin, nor is he involved in the sins of humanity. The work of Christ is a finished work. When he finished providing salvation for fallen man he returned to heaven where he is mediating his atonement for our sins and his righteousness on our behalf, Hebrews 1:3.
Jesus is our legal advocate. He is our representative. If we did not have legal representation we would all be without hope. Jesus in our name and on our behalf, offers to God the Father a life of perfect obedience according to his Holy Law. He did this for our justification. Because of the doing and the dying of Jesus we can now stand before God's holy court as legally justified and saved.
That was not enough. In order for us to be legally saved something must be done about our sins and the sins of the whole world.
"For he has made him (our representative) to be sin for us, who knew no sin; that we might be made the righteousness of God in him" 2 Corinthians 5:21.
The ultimate price for the sins of humanity has been satisfied by the death of Christ. The law has been fulfilled, Matthew 5:18. and abolished, Colossians 2:14. Our sins and the sins of the whole world have been atoned for, 1 John 2:2. Because of the doing and the dying of Jesus we can now stand before God's holy court as perfect and complete "In Christ".
