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.
It is not finished for those who do not repent. It is not finished for those who reject God’s offer of peace and forgiveness. It is not finished for those who call God a liar and who rejoice in their sin and promote sin to others.
“Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of Gods one and only Son.” - Jesus
“The man who believes in the Son has eternal life. The man who refuses to believe in the Son will not see life; he lives under the anger of God. - Jesus
