I'm glad you want to give your life to Jesus and so I want you to know that God loves you very dearly.  Put your name in the dotted spaces in the verse from John 3:16 below, and say it out loud:

"For God so loved ( your name ......... ),
that He gave His one and only Son, Jesus Christ,
that if ( ........ ) believes in Him, ( ........ ) will not perish,
but have eternal life in Heaven."

God wants you to turn away from your sin and do things His way.  Sin is disobeying God and doing wrong things.  You need to realise that unless you give your life to Jesus, you will be separated from God forever when you die.  Romas 3:23 says:

Do you believe that Jesus died on the Cross to forgive your sins, and that He rose again, proving that He is the Son of God?  If you do, you will realise that only Jesus can forgive your sins and that He is the way to Heaven.  We read in the Bible that:

If you decide to give your life to Jesus, then you need to tell Jesus that you have sinned, and ask Him to wash your sins away and make you clean inside.

Now ask Jesus come into your life as your Saviour by saying this prayer out loud:

Dear God,
I know I have done wrong things.  Please forgive all my sins and make me clean inside.  Come into my life and be my Saviour, Best Friend and Lord.  Change me into a child of God, and make me into the kind of person You want me to be.  I know that when I die, I will live forever with You in Heaven.  Help me to read the Bible and talk to You every day, so that I can please You in all I do.  I receive this now in Jesus Name, Amen.

Believe and know that Jesus has come to live in your heart.  Trust God to do what He has promised in the Bible.  Say out loud, "Jesus has forgiven my sins and made me clean inside, and now I'm a child of God, and have a place reserved for me in Heaven".

"For it is by grace (God's loving kindness) that you are saved through faith.
It is the gift of God, not by what you do" (Ephesians 2:8-9).

Make sure you serve Jesus and please Him every day.  Grow as a Christian by talking to God each day in prayer, reading your Bible (start in Luke's Gospel), and going to a Sunday School or Children's Church each week.  Don't forget to tell your friends about Jesus and what He has done for you!

God bless.
