How do we know the gospel is the true sustenance for believers?
Answered in 1 source
The gospel is true sustenance for believers because it reveals Christ's body and blood as the only means by which sinners are made righteous.
The preaching of the gospel is essential because it conveys the only life-giving sustenance—Jesus Christ's body broken and blood shed for His people. This message is supported by Scripture, which teaches that true life and satisfaction come only from faith in Christ’s finished work. As stated in John 6:51, Jesus claims, 'I am the living bread which came down from heaven: if any man eat of this bread, he shall live forever.' This divine sustenance is not merely physical but spiritually nourishing, enabling believers to partake in eternal life through Christ. The righteousness of Christ is imputed to the believer, fulfilling their greatest need and aligning with God's gracious provisions for His elect.
