How does salvation affect assurance of faith?

The assurance of one's salvation is rooted in the understanding that it is God's doing, not ours. According to Ephesians 2:8-9, we are saved by grace through faith, and this is not our own doing but a gift from God. Believers often struggle with doubt when they focus on their works or feelings instead of Christ's finished work. Assurance comes by continually looking to Christ, acknowledging that salvation belongs to the Lord. As Jesus assures us in John 10:28-29, no one can snatch us from His hand, reaffirming that our security in salvation is a result of His faithfulness rather than our fluctuating faithfulness. Thus, confidence in salvation is interconnected with understanding its divine origin and ongoing nature.
