I've known a few people who have bought fixer-upper houses. Sometimes they're in such bad condition that you can't even live in them, at first. But with time, investment, patience, and hard work, the homeowners turn them into something beautiful.
This morning I was thinking about how similar this is to what God does for us. When He calls us, He redeems and justifies us. Then, over the rest of our lives, He fixes us up. No doubt that takes a lot of patience! He doesn't do this in order to sell us for a profit, but to turn us into beautiful places for Him to live.
However, I see a major difference between our sanctification and the fixing up of a home. Usually a fixer-upper home is purchased at a low, low price, because its value isn't very high. It'll require a lot of work. But God redeemed us at the highest price, the sacrifice of His own Son! And then He proceeds to invest in us to turn us into something beautiful.
People often say, "I'm a work in progress." In Christ, we really are. He's not finished with me yet.
