If I was to imagine God as a mechanic I would see Him with tools and helpers. He uses both to get His work done.
Sometimes He asks us to do something and we do, and that gets it done. Just like a real mechanic can do the work himself, God does not need us. However, out of His grace, He chooses to use us. “Hold this.” “Bring me that.” “Loosen this.” “Tighten that.” We learn more about how the machine (which He created) works and more about how He works. It is great to be a helper for Him. In fact it is the most fulfilling endeavor you will ever take, because that is why we were created. (Ephesians 2:10, Philippians 2:13)
Following on the heels of helpers, and using the same scriptures, it is not hard to see that there are also tools that God uses. The difference between a helper and a tool is that the tool has no will. The tool just is. It makes no choices as to what it will do, it is merely an object in God’s hands. I think more often we are just a tool.
If feels a lot better to be a helper than a tool. Do we have a choice in the matter? I think we do. I think by watching and listening to the Master we can learn how to be a helper and not merely a tool. We can learn what comes next in the process. We can listen to the sounds of the machine. We can be willing and not inanimate.
He is going to use you either way, which are you going to be?
