Why is inner change important for Christians?

The sermon underscores that the change required for a believer is not merely outward reformation but profound inner transformation facilitated by the Holy Spirit. This change is described as moving from a legalistic approach to obeying the law to one rooted in love and grace. In Galatians 5:22-23, we see that the fruit of the Spirit brings forth love, joy, and peace, indicating that true obedience stems from a heart transformed by God. This inner change not only releases us from the condemnation of the law but empowers us to live in a way that glorifies God.
