Our attempts to save ourselves by works of the law are, in essence, attempts to rob God of His glory. - Portia Collins
Paul’s writings in his letter letter to the Galatians serve as a stern warning against the sin of legalism. While it may be easy to think of this as an issue of the past, many wrestle with legalism just the same today.
Any attempt to obtain justification by means apart from the grace of God is sinful. At the core, our efforts to make ourselves right by works of the law are attempts to rob God of his glory.
The gospel is such an offense to man because it shows us that we are utterly incapable of earning our salvation. It reveals our neediness. It shows us that we aren’t the heroes in the story; God is!
