How does preaching lead to spiritual healing?

Preaching is vital in the process of salvation as it communicates the Gospel, which is the power of God unto salvation for everyone who believes (Romans 1:16). According to 1 Corinthians 1:21, God chose to save through the foolishness of preaching. When the Gospel is proclaimed, it opens eyes and ears to the truth of God’s Word. Jesus Himself preached the Gospel during His ministry and healed those who came to hear Him. This illustrates that spiritual healing begins with the proclamation of the truth, enabling individuals to recognize their need for salvation and to respond by faith.
