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

Hebrews 12:2 portrays Jesus as the author and finisher of our faith, indicating that our faith begins with Him and finds its completion in Him. He has not only authored our salvation through His life, death, and resurrection but also ensures its maturation and perfection. In 1 Peter 5:10, we see that God will perfect, establish, strengthen, and settle us, demonstrating His active role in our spiritual journey. Our reliance on Christ for faith and salvation underlines the sovereignty of God in every aspect of our lives.
