The Bible tells of God’s desire to create paradise on earth, of man’s decision instead to thumb his nose at God, ushering into our world that 3-letter word which we love to do -- but resent being accused of S-I-N.
God, as we read on, loves us too much to let us suffer the eternal consequences of sin (which are separation from Him in a place the Bible calls hell). To erase this not-so-hot outcome, God sends His Son Jesus to pay with His own life the awful price to have our sins forgiven forever.
