K.P. Yohannan emphasizes that the story of David and Goliath is not just a childhood tale but a profound lesson in dependence on God. David, a young boy without military experience, faced the giant Goliath not with weapons or skills, but with unwavering faith in God's power. This narrative illustrates that God often chooses the seemingly unqualified to accomplish His purposes, as seen in the lives of David and Noah, who relied solely on God's guidance. Yohannan encourages believers to trust in God's ability to work through them, regardless of their credentials, highlighting that true qualification comes from a heart that depends on Him. Ultimately, God desires to use ordinary people to manifest His extraordinary power.
