I've run into a couple of people recently that have caused me to reflect on grace. There are many well meaning Christians who have bought into legalistic teachings that make performance more important than grace. They are under grace as people who follow Christ, but they operate like they are under the law. They work hard to earn what Christ has given freely. They punish themselves for failure though Christ paid for those failures on Calvary. They see themselves as a big disappointment to God, though God sees them as the objects of his love. How could we get this wrong!?
In John 1:17 it says, "For the law was given through Moses; grace and truth came through Jesus Christ." The law taught people that they could never be found righteous through rule keeping, but Christ taught people that they no longer had to try. It's switched around now. We are found righteous by the grace of Christ Jesus! We follow his teachings (yes, there are some rules) now because we want to, not to earn his favor.
