How does God create the fruit of the lips in believers?

According to Isaiah 57:19, God declares, 'I create the fruit of the lips.' This signifies that the genuine expressions of faith, including confession, praise, and prayer, are not the result of human effort but are created by God Himself through His Spirit. The new birth is a transformative act where God imparts spiritual life to the believer, enabling them to produce fruit that aligns with His will. Paul reflects this in Galatians 5:22-23, where the fruit of the Spirit is evident in a believer's life, further underscoring that these qualities originate from God's sovereign grace rather than natural abilities.
