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

Hebrews 12:2 presents Christ as the 'author and finisher' of our faith, meaning that He not only starts our journey of faith but also brings it to completion. This is consistent with the broader biblical narrative that portrays Jesus as the Alpha and Omega, the beginning and the end (Revelation 22:13). His work is perfect and sufficient, ensuring that all whom He begins a good work in will see it completed (Philippians 1:6). This assurance rests in His sovereign power and commitment to His people, affirming that He will fulfill every promise made to them.
