What is the role of faith in a believer's life according to the sermon?

In the sermon, the importance of faith is emphasized as the means through which believers receive both justification and sanctification. Paul notes in Galatians 2:20 that while we are crucified with Christ, we nevertheless live by faith in the Son of God, who loved us and gave Himself for us. This relationship underlines the dynamic of living by faith, where the believer’s trust in Christ’s work ensures both their present walk and future hope. Faith is not a mere initial act but an ongoing reliance on Christ, empowering us to bear fruit and live in light of our new identity in Him.
