The sermon centers on Jesus' profound question to the twelve, 'Will ye also go away?', following the departure of many disciples who were drawn only to His miracles, not His truth. It emphasizes that true discipleship is rooted not in spectacle or temporal gain, but in faith in Christ as the source of eternal life, whose words alone offer spiritual sustenance and everlasting hope. The passage underscores the sovereignty of God in salvation—highlighting that no one can come to Christ unless drawn by the Father, and that both the elect and the reprobate are known to God from eternity. The confession of Peter, 'Lord, to whom shall we go? Thou hast the words of eternal life,' stands as a model of unwavering allegiance to Christ, the only source of truth, comfort, and eternal life, in contrast to the fleeting and fallible words of men. The sermon concludes with a sober yet hopeful reminder that even within the chosen twelve, one was a devil, illustrating that hypocrisy can exist even in the most faithful communities, yet the majority remain faithful, sustained by the enduring word of God.
