New wine in old wineskins

So I bought this new race car about 3 years ago. I did not at all like the paint scheme of the car. It had a lot of blue, with yellow, white and red striped going down the side. It wasn't even a blue that I particularly liked, but I got such a good deal on the car and it was exactly what I wanted at the time. The same went for my last car, my first true race car that I ever purchased was 2 different shades of green and I am not a big fan of green, especially green race cars. So I had a dilemma, do I paint the car or do I get them running.
With my first race car I was currently racing my dad's car so I wasn't in a huge hurry to get it running, I took the time to get the motor together, get it running right and paint it all before it ever hit the track. Then, when I bought my second car I was without a race car, no ride, ready to race so I started out racing it with the motor we already had and didn't bother painting it. I raced it like that for about a season and a half before I could paint it. It wasn't until I had it painted the way I like it and running the way I wanted that I was truly proud of it and enjoyed it to the fullest.
It's that way with God, he puts us together with a purpose. Until the inside is right with God, we are not usable by Him. He needs us to make a decision not only to choose Him as Lord and Savior but to let Him have control over our daily lives. We start out with a change on the inside, with a new life growing inside of us ready to bust out into the environment we live in. But, it's not until our lifestyles change, our outward attitudes and daily routines must change before that inward growth can manifest itself in our lives.
Matthew 9:15-17 No one sews a patch of unshrunk cloth on an old garment, for the patch will pull away from the garment, making the tear worse. Neither do men pour new wine into old wineskins. If they do, the skins will burst, the wine will run out and the wineskins will be ruined. No, they pour new wine into new wineskins, and both are preserved.
Think about it, what good is a new life in Christ if we are daily doing things that negate the changes that are taking place in our lives. What possible good can come from someone telling people about Christ, about how He has changed their life if they don't appear to have changed. It's a packaged deal, neither is any good without the other. Eventually, the "new wine" or "new life" will spill out and bust the old skin and it will be evident to all what has taken place, and how much you have allowed your flesh to overrule your heart.
So live in a way that brings no shame and no discontent to your new life that is found in Christ, that way you are usable to God in whatever you do.
Thanks for reading and have a great day!
