A Pastoral Warning About Apostasy

This sermon, drawn from Galatians 4:8–11, delivers a sobering yet pastoral warning against the peril of apostasy—returning to a religion of works and legalistic observance after experiencing the liberating grace of faith in Christ alone. It emphasizes that true conversion is not a mere religious shift but a radical transfer from slavery to false gods into intimate, relational knowledge of the living God, secured by His sovereign, electing love. The preacher underscores that any attempt to add human effort, ritual, or religious duty to justification by faith alone is not merely a mistake but a form of spiritual slavery, a return to the very bondage from which Christ has redeemed believers. By contrasting the sufficiency of Christ's finished work with the futility of legalism, the sermon calls Christians to stand firm in gospel liberty, rooted not in performance but in God's unchanging faithfulness, and to guard against the subtle temptation to exchange grace for works, which ultimately undermines the very foundation of salvation.
