The very reason Jesus came to earth was to free us from our sins, because each and everyone of us is guilty of putting our own selfish feelings first and not the will of God. Each of us is guilty of sin and without divine intervention there is no other way than down–we can only go from bad to worse.
What has happened? If God is perfect and everything He created was good, then why is there so much pain and suffering in the world? Did God intend for the world to be like this, so full of sin?
