Then you need to find a Christian and tell that person these things. After you have become a Christian in this way, it is important that you get a Bible and read it, starting with the New Testament, to learn more about Jesus and how to live as a Christian. You will need the friendship and support of other Christians. Some Christians will be older and stronger in the faith and some will be new and weak and confused, like you. God takes every new Christian into the family like a new baby.
Babies have to grow up.
It will take time and you will fall down a lot, just like a baby learning to walk. I'm just a Christian, still growing in understanding and still working toward perfection.
