How do we know that believers in Christ go to heaven?

Scripture repeatedly affirms the promise of eternal life for those who trust in Christ. In 1 Corinthians 15:54-57, Paul outlines how death is swallowed up in victory because Christ has conquered sin and death through His own death and resurrection. Believers are assured that their faith in Christ secures for them a place in heaven. This assurance is not based on their works, but on Christ's finished work. Therefore, when believers pass from this life, they enter into the fullness of life with God, free from sin and suffering.
