That doesn’t matter. God was concerned about them before they responded to Him in Ninevah.
“While we were yet sinners, Christ died for us.”
God’s concern is either real or it is feigned.
God constantly pours His riches out on us day after day after day. The truth people don't care. Rom 1:21 For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.
As Dr. E used to say, "If God wanted everyone saved, they would be saved." Do you think it is loving of God to send people to hell? From my perspective, there are many that would rather reign in hell then serve in heaven. As such, as difficult as it is to fathom, there is not one person who will be misplace or regret where they end up. This is the wisdom, love, grace, and justice of God.
