Giving you life to Jesus means to ask him into you heart. You said you pray once in awhile and believe in God. That good!
O.K Now I have to let you know there is a thing called Repent and Confession
That means that we must admit that we are sinners. Everyone is a sinner. A sinner is one who does wrong agaisnt God. You are very young, so you may not have done much to understand, but when you grow up you will need Jesus to forgive you of these wrongs. I do and will always need him. Secondly, confession means believing that Jesus is God’s only son.
If you understand so far, you can read on if you like.
Next time when you pray ask Jesus to make you one of his kids. You can say this if you chose “Jesus I believe you are God only son. I believe you will forgive of the wrong things I have done and will do. Forgive me Jesus. Come into my heart and change me. Teach me to honor you all the days of my life. Amen.”
I hope this is simple to you. Please let me know if you have prayed or have any more questions. And remember Jasmin, God loves you and Jesus loves you.You may be 12 but Jesus will hear you when you pray for him to make you one of his kids.
Take care, young lady.
