Get Baptised. This doesn't just get you wet, it seals your relationship with God & He'll never leave you nor forsake you. It'll also make your own Guardian Angel deliriously happy.
Ask God to lead you to a good Church because you will learn more about him if you hang out with his people.
Say sorry to God for the things you've done and invite Jesus into your life.
Acknowledge that you have done things in your life that have caused you to be separated from God. (The Bible calls this Sin)
When you understand who Jesus is and what he did, tell God that you believe him and say thank you for what he's done for you.
As you read it, ask God to help you understand what's true. (Do not go to the next Step until you've got it).
Read one of the books in the Bible. 'Matthew, Mark, Luke or John'. This is the story of how God sorted out the problem of "You" being separated from "Him".
Get a Bible, unlike most books it's stood the test of time. If God had anything to do with just one book it's the Bible.
Allow for the fact that in a relationship God might want to talk back to you. It's the way relationships grow.
Start talking to God, about everything. it's the way relationships get going.
Consider that this power might just be a person called God who might want to know you.
Accept that there might just be a power greater than yourself.
