You're not here by accident. Jesus loves you, and He wants you to have a personal relationship with Him. There is just one thing that separates you from God. That one thing is sin.
People tend to divide themselves into groups - good people and bad people.
But God says that every person that has ever lived is a sinner, and any sin separates us from God. That includes you and me. For all have sinned and come short of the glory of God. According to man's rules, people should be punished or rewarded according to how good they are, and it might be hard for you to understand how Jesus could love you when other people don't seem to. For you to come to God you have to get rid of your sin problem.
