During the past couple years, my perspective has been changed. There's not a single event that flipped my switch. Maybe it was me seeing people left out to rot, because grace couldn't be offered to them. Maybe it was when I looked in the mirror and saw how ugly I was when a close friend needed grace. I had allowed my piousness to bring out the worst in me.
Here's what I've learned. Grace isn't a piece of a larger puzzle, but it's the entire story. It's how we get from Point A to Point B. How does the fallen man in Genesis transform to the man who fellowships with God in Revelation? Grace. There's nothing man has done to make him worthy. Why should we restrain the grace we extend to others for any reason? Paul said his life would be worthless if he didn't testify to God's grace (Acts 20:24). I don't encourage you to practice grace. I encourage you (and myself) to live it with no limits.
Grace makes beauty out of ugly things.
