Christians are assured of their salvation because it is based on the finished work of Christ and God's promises.
Assurance of salvation for Christians is anchored in the finished work of Christ on the cross and the promises of God as revealed in scripture. Through His sacrifice, believers are redeemed from the curse of the law and declared righteous before God. This salvation is not contingent upon human effort but solely on God’s grace. In 2 Corinthians 1:20, we see that every promise of God, including salvation, is fulfilled in Christ, providing believers with confidence that their position in Him is secure. The Holy Spirit affirms this truth in the hearts of believers, offering the assurance that those who are in Christ cannot fall away but are eternally loved and protected by the Father.
