It's as simple as A, B, C.

A: Admit that you have sinned against God.

  • For all have sinned and fallen short of the glory of God. Romans 3:23

  • For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. Romans 6:23

 

B: Believe on Jesus Christ to save you from your sins.

  • For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life. John 3:16

  • But God demonstrates His own love for us in this: While we were still sinners, Christ died for us. Roman 5:8

 

C: Confess your sins to God in faith that He will forgive you.

  • If we confess our sins, He is faithful and just and will forgive us our sins and purify us from all unrighteousness. I John 1:9

  • Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ. Romans 5:1

 

You can know for sure that you are saved and going to heaven.
