How do we know that Jesus is our source of spiritual nourishment?

In the sermon, Jesus is compared to a source of rivers of water in a dry place, which signifies His role in providing spiritual nourishment to His people. Just as God provided physical sustenance to the Israelites in the wilderness, Christ offers His words as spiritual food, which are essential for life (John 6:63). These words are spirit and life, sustaining the believer in a world that is often barren and unfulfilling. Jeremiah 15:16 expresses the joy that comes from consuming God's word, further emphasizing that true satisfaction for the believer is found solely in Christ and His promises.
