The Children of Covenant Liberty

Cameron Porter · Galatians 4:21–31

Why would anyone seek salvation through law when the law itself testifies to salvation by promise alone? Paul confronts the Galatians with this piercing irony as they drift toward Judaizing error, using Abraham's two sons to expose the fundamental distinction between covenant bondage and covenant liberty. Through careful allegory, he demonstrates that Ishmael and Isaac represent two entirely different covenants—the legal Mosaic covenant that produces only slavery, and the covenant of grace that births true freedom in Christ. Christians must cast out every vestige of legal confidence and stand fast in the liberty that belongs exclusively to the children of promise.
