The carrot! "Don't we all desire a better world where we can live in peace and have everlasting life on earth"? That is our desire and what we pray for to God and the reason his son came down from heaven in the form of a man. Jesus gave his life that we may live.
Why is it taking so long? God cannot blame us who want peace and life for having doubts as it has been 2000 years since the promise...and what do we have? I CAN see your point. The concept of a burning in hell for the wicked (those who had a bad upbringing) is totally UNFAIR and then the GOOD ones aren't good enough to go to heaven. We all sin. Yes, I agree we really need for God to show his self to us. The words in the Bible is not enough.
