Being sure of heaven and being born again is as easy as
All you have to do is:
Admit that you are a sinner (made a lot of really bad mistakes) and need forgiveness from up on high.
Believe that Jesus Christ died for you on the cross and rose from the grave to bring you to God.
Confess, through prayer, that Jesus Christ is the only way to God, and commit to live for Him the rest of your life.
Here are some words from the Holy Bible (New International Version) that talk about our problem.
God loves you and wants a personal relationship with you. (John 3:16 NIV)
Our sin keeps us from having a personal relationship with God. (Romans 3:23 NIV)
Jesus is the only answer to this problem. He’s the only one who can bring us back to God. (1 Peter 3:18 NIV)
You must personally trust Jesus to forgive your sins and determine to obey Him for the rest of your life. (John 1:12 NIV)
I know I have done wrong and need your forgiveness. I believe that you died on the cross just for me so I can come to your place in heaven when I die here And then you rose from the grave to give me eternal life too. I know You are the only way to Heaven, so help me to quit disobeying You, Your Dad The Father God, and Holy Spirit God and to start living for You. Forgive me, take over my life, and make yourself real to me. Amen.
P.S. I would like to be your friend too.
