Doing what He wants

I am reading a very good book by David Orton called 'Snakes in the Temple'. In it he explores how Satan has got into the church through hidden idolatry. He talks about the fact that we are all familiar with the idea of doing bad things outside the will of God but that the idea of actually doing good things can also be outside the will of God. He quotes Matthew 7:22-23 'Many will say to Me on that day, "Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?" And then I will declare to them, "I never knew you; Depart from Me.' Here Jesus is actually saying that even if we are operating in the supernatural we can still be outside of God's will for us. How many of us can even say that we prophesy, cast out demons and perform ANY miracles let alone MANY and yet Jesus says to these people that He doesn't know them. We can do all manner of wonderful things but if God hasn't asked us to do them then we are outside of His will. 'To obey is better than sacrifice' (1 Samuel 15:22) Again Jesus says in the previous verse in the book of Matthew 'Not everyone who says to Me, "Lord, Lord", will enter the kingdom of heaven; but he who does the will of My Father...' It made me think really hard about what I am doing and why. I want to make sure that whatever I do is because the Father has asked me to.
