Why must we rely on Christ for spiritual sustenance?

The sermon highlights our need for Christ by comparing our spiritual hunger to physical hunger. Just as the Israelites could not survive in the wilderness without the manna from heaven, Christians cannot thrive spiritually without the sustenance provided by Christ. John 6 elaborates on how Jesus presents Himself as essential for life. The text underscores that without partaking of Him—believing in Him and His redemptive work—one cannot have life. The living bread represents the totality of what believers need for justification and sanctification, affirming that all spiritual needs are met in Christ alone.
