In Galatians chapter three Paul addresses the person that believes they can earn righteousness with God by keeping the law. "If you want the law, that's fine, but know this: If you don't obey ALL of the law, you're cursed!"
But those who depend on the law to make them right with God are under his curse, for the Scriptures say, "Cursed is everyone who does not observe and obey all the commands that are written in God's Book of the Law." So it is clear that no one can be made right with God by trying to keep the law. For the Scriptures say, "It is through faith that a righteous person has life. Galatians 3:10-11
The problem is that none of us can perfectly keep the law. Try and go one day without sinning, or even one hour! You may do fine for a little while, but sooner or later you're going to slip up and get angry, or have an impure thought. Its pretty much an "all or nothing" deal; God doesn't grade on a curve!
That doesn't mean the law is bad, or without purpose. In verse 19 Paul tells us why the law was given:
Why, then, was the law given? It was given alongside the promise to show people their sins. Gal 3:19
The law simply reveals the reality that we all know, we aren't perfect, and we'll never be able to perfectly keep the law. And that's the beauty of the gospel message; It doesn't command us to be perfect, only to believe. See...
If the law could give us new life, we could be made right with God by obeying it. But the Scriptures declare that we are all prisoners of sin, so we receive God's promise of freedom only by believing in Jesus Christ. Gal 3:21-22.
I don't know about you, but I'm so thankful God didn't expect me to keep an all or nothing deal, but instead offered me a "all and all" deal; I believe all that God says about His Son Jesus Christ, and in return I receive all of the righteousness of Christ. #WIN
"Lord, thank you for the promise of freedom that you gave me in Jesus Christ."
