Believe it or not, Christianity is not about good people getting better. If anything, it is good news for bad people coping with their failure to be good.
In the Old Testament, we are continually told that our good works are not enough, that God has made a provision. This provision is pointed to at every place in the Old Testament.
Indeed, there is nothing like suffering to remind us how much we need God. What good news that His purpose and plan for our lives moves in a different direction from ours!
