How Can We Truly Love God in Heaven if We Won’t Have the Free Will to Reject Him?

Questions about whether regeneration counters total depravity in the Reformed view and how it could be that we’ll truly love God when we’re in Heaven, where we can’t reject him, if real love requires the free will to reject him.

• In the Reformed view, does regeneration counter total depravity, or is a regenerate person still totally depraved?
• If we have free will to reject God because one cannot love someone without the choice to reject, wouldn’t we then not have the ability to truly love God in Heaven?
