How do we know that Christ is the author and finisher of our faith?

Scripture declares that Christ is both the author and finisher of our faith (Hebrews 12:2). This signifies that He initiates our faith by calling us to Himself and sustains it throughout our lives. His redemptive work on the cross is central to this, as He bore our sins and reconciled us to God. Furthermore, Philippians 1:6 reminds us that He who began a good work in us will complete it until the day of Christ Jesus. Therefore, our assurance lies not in our efforts but in the finished work of Christ, who guarantees our faith from beginning to end.
