You can't join.  You have to be born into God's family, you know, born again.

So how can you be born again? 

1 Peter 1:23 says that you must be born of incorruptible seed by the word of God.

John 1:1 says that Jesus is the Word. You need to be born of Jesus, the incorruptible seed, who is the Word of God.

Romans 10:9 says that if you confess the Lord Jesus with your mouth, and believe in your heart that God has raised him from the dead, you shall be saved.

Will you, just now, confess with your mouth that you have sinned and that you need a Savior for forgiveness and deliverance from your sin? Will you tell Jesus that you will receive Him right now?

Just pray, "Jesus, I receive you and turn my back on all my sin.  I have been wrong.  Please forgive me and give me a new heart.  Please redeem me from my slavery to Satan and set me free from bondage to sin by the power of the blood you shed for me.  Come, Lord Jesus and live in me and let your Light shine out through me."

That may seem too easy, but it's the only way.  You see, we didn't really have anything to bring to the situation other than a willingness to be reconciled to God.

Don't miss out now.

It's a wonderful thing to be born again.
