People of all times, places and religions have instinctively known that there will be a final judgment and reward or punishment after death. This knowledge is built right into us.
Heaven and hell are logical extensions of God's character:
• God is HOLY. He has established good and consistent physical and spiritual laws we can depend upon.
• God is JUST. There is penalty for wrong choices. Hell (total separation from God after death) is the penalty for a lifetime of sin.
• God is LOVE. He offers a substitute (Jesus) to free us from the penalty. If we accept, we get heaven instead of hell.
The substitution is a gift, and hell is what's left if the gift is rejected.
It's only within the last 60 years that science has acknowledged that the earth has NOT ALWAYS EXISTED but rather had a formless beginning from massive external power, just as the Bible has said all along.
It's highly unlikely that any writer three thousand years ago could know about the big bang without divine revelation from the designer/creator.
Scientific comfirmation increases confidence in the Bible and provides another REASON for Christian faith.
