One of the most frequent objections to UR is couched in questions regarding the fate of especially evil people who have committed atrocities against other humans. If UR is true then does that mean Hitler/Osama gets into heaven?
Usually, if not always, the person asking such a question is already a believer, a Christian. Thus I often reply asking them a question, “Well, let me ask you; if Hitler, seeing all that he built collapse around him, knowing his days were over, remembered the prayers of his mother and the words of forgiveness in scripture he read as a child, repented and turned to God asking for forgiveness, moments before the bombs fell and killed him, would he be forgiven and go to heaven?”
And if Osama, moments before he was killed, happened to recall the Gospel he heard from some Christian he met in college, and the lights came on and he understood the love and forgiveness of God, was broken and repented, but then was killed, would he be forgiven and go to heaven?
Paul wrote, “And the grace of our Lord was exceedingly abundant, with faith and love which are in Christ Jesus. This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief. However, for this reason I obtained mercy, that in me first Jesus Christ might show all longsuffering, as a pattern to those who are going to believe on Him for everlasting life.”
Saul, in many ways the Osama of his generation, did not die at the hands of the Romans, but did “die” through encountering our risen Lord Jesus. Saul experienced the judgment of the Lord and was changed, delivered from evil, and set on a path of loving service for God and others. He encountered the Truth and the Truth, well, burnt the hell out of him and changed him forever! Saul even changed his name to Paul.
So the issue is not how much a person has sinned, but how much do we trust in the forgiveness and love of God, not only for ourselves, but for others also.
