Throughout the centuries, God has given us all a blue print as to how we are to live, behave, treat each other, etc. But many have chosen to reject it and do whatever they want, treat people in any way they want, and sin anyway they feel like believing that they won't suffer any repercussions of their doings. If we accept Jesus Christ as our savior and realize we all have done wrong and fell short of God's glory and ask forgiveness and change our minds about sinning (repenting), then we will live with God forever after our death. If we choose otherwise, the penalty is Hell, and it's no joke. It's eternal, it's very painful physically and emotionally, and it's a place of lost hope and lost dreams. It's not worth going to Hell for eternity to have temporary pleasure here on earth that's not in a Godly way.
