But that's not entirely true. There are billions of people down through the ages who have made the choice to accept Christ as Savior.
We are born into this world with a sin nature and bent away from God, but God always gives us a choice to freely accept Him and follow Him or not. God gave Adam and Eve a choice to obey Him, and He has given each and every human being since then a choice.
The fact that more people will choose death over life, which God tells us will happen, is no reflection on God, nor does God make that choice for those people.
From our perspective this is the way that it appears-we make a choice for God. But if you were to step back and look at what really happens, the Spirit moves where it will. That is why Aunt Myrtle comes to Christ but not Uncle Bill even when they hear the same scripture verse. God had mercy on Aunt Myrtle but to Uncle Bill God leaves him in his fallen state for justice. It would appear to us that Aunt Myrtle (and indirectly Uncle Bill) have made choices. Rather consider that the Holy Spirit worked on Aunt Myrtle's heart and granted her faith to move her to salvation. She accepted Christ because she saw the light and wanted what it offered-not unlike Paul on the Damascus Road or Moses before the burning bush. Salvation is and always has been the same experience throughout history. It just comes packaged differently.
Why God chose to show Aunt Myrtle mercy can only be summed up in the providence of God. He is the potter and we're the clay.
