If you are a professing Christian, I would ask you where you got that notion from? Certainly not from Scripture, nor the teaching of the historic Christian faith.
Also, if that sentiment were true, and God did separate the sin from the sinner, hating the sin and loving the sinner, then why does God assign that sin to the sinner and banish them to hell for their sin?
I am really curious as to your response.
God doesn't banish people because of their sin. He banishes them because they reject the Holy Spirit. That's the only sin that keeps them out of heaven. What does happen with sinners is that they lose out on his blessings here on earth because they walk their own way. They don't see the Kingdom of God on this earth because they won't obey and walk the way God wants them to. If they repent and turn away from their sin, they can once again be blessed by the God who does love them. He doesn't want anyone to perish but because he is a just God, he allows them to when they refuse his Holy Spirit.
