I don’t know all of the theological/doctrinal implications that come from the idea of a conditionally forgiving God.
I am not a biblical scholar by any means.
But, let me say that I do not believe that unforgiveness results in a total separation from God, or salvation. That kind of swift, hard judgement doesn’t align with the character God that the rest of Scripture describes.
God is patient, kind, just, long-suffering, and knows our human frailties. Romans 8 says that nothing can separate us from the love of God. Especially not something as common as sin struggle.
However, as every action has a reaction, every sin has a consequence. And, I don’t believe that we are removed from our consequences because of the love of God. Scripture shows that through the experiences of David and Bathsheba, Moses and the promised land, Abraham and Ishmael, etc.
