A lesson that reminds us that from beginning to end, we need the Gospel; we need to behold Christ and Him crucified, knowing that the grace that saved us also sustains us on the journey to glory. The sermon centers on the enduring truth of justification by faith alone in Christ alone, emphasizing that salvation is a gift of grace entirely dependent on Christ's finished work, not human effort. Drawing from Galatians 3, it confronts the persistent temptation to add works or self-reliance to faith, warning that such deviation—whether from external false teachers or internal pride—amounts to spiritual foolishness and a betrayal of the gospel. The preacher underscores that the Christian life begins and continues by the Spirit through faith, illustrated through the Galatians' own experience of receiving the Spirit, enduring persecution, and witnessing miracles—all by hearing with faith, not by law-keeping. Ultimately, the message calls believers to daily fix their eyes on Christ crucified, recognizing that the same grace that justifies also sanctifies, and that the gospel is not only for the beginning of faith but for the entire journey of life.
