Those who worry about heaven are missing the point. It’s not about what we’re doing to get to heaven. It’s all about the cross, and what Jesus Christ, the Son of God, has already done for all men, past, present and future by dying in our place for the remission of sins. The work of Jesus on Calvary is complete. Nobody ever gets to heaven by their works. Eternal life in heaven is a gift of grace from a loving, merciful God. All we have to do is believe in the gospel of Christ by faith and ask Jesus Christ to be our Lord and Savior. God judges the heart and once He knows your faith is true you are saved unto eternal life at that moment. Your name is irrevocably added to the Book of Life.
Eph 2:8,9 – For by grace you have been saved through faith, and not of yourselves; it is the gift of God, not of works, lest anyone should boast.
John 6:37 – The one who comes to Me I will by no means cast out.
Rom 11:29 – For the gifts and the calling of God are irrevocable.
Acts 16:31 – Believe on the Lord Jesus Christ, and you will be saved, you and your household.
1 Thes 5:9 – For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ
Rom 10:9 – That if you confess with your mouth, Jesus is Lord, and believe in your heart that God raised Him from the dead, you will be saved.
