"Corrosion"
I spent most of my Saturday putting new brake pads and rotors on the family SUV. It's a pretty mechanically simple job and since brakes aren't covered under warranty, and the dealership wanted eleventy billion dollars (their exact quote) for the job, I gladly took the job on. I actually was in a warped way looking forward to the job since I am usually found working on some 40+ year old rusty, crusty, VW. I actually thought working on a clean, 3 year old, vehicle would be a "piece of cake". I was wrong...
Corrosion had already set in, even on this relatively new , pampered vehicle. Every bolt was a struggle, every possible part was "stuck". I spent at least 2 hours of the day just beating on the brake rotors with a very large hammer to "persuade" them to come off even after all the bolts were removed.
I think our hearts are like that. I think it takes a very short time to become "corroded" and "hardened", and a whole lot of "persuasion" by God's Spirit to "soften" us. I think in a very short time we can become cynical. I think in a very short time we can lose hope. I think in a very short time we can lose our "childlike" faith that in "partnership with our creator" we can actually change the world. I think our lives are filled with "corrosive agents" that make it very hard for God to do his "work" in our lives... I know it's something I have to deal with every day. How about you?
12 Be careful then, dear brothers and sisters. Make sure that your own hearts are not evil and unbelieving, turning you away from the living God. 13 You must warn each other every day, while it is still “today,” so that none of you will be deceived by sin and hardened against God. Hebrews 3:12-13 nlt
