Oh, I understand and am deeply grateful that he took my sins, but if he had not risen he wouldn’t be God. The resurrection, ascension, and His return are all necessary.
Your comment: “but if he had not risen he wouldn’t be God”
I disagree with your comment.
Jesus was always God and he proved it by His word, his actions and His teachings.
The Resurrection proved that God and that humanity had eternal life and that He conquered death.
Yes His resurrection helped many believe in Jesus and follow Him, but His death and suffering opened up Heaven for the righteous that had died before His death and for those that died after His death to join Him in eternal life.
