"The Will of My Father"

The other day I was reading in Matthew and I read this passage:

Matthew 7:21-23
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' And then will I declare to them, 'I never knew you; depart from me, you workers of lawlessness.'"

This passage frightened me. Jesus says that only the one who does the "will of my Father" will enter the kingdom of heaven. Then he says that there will be people that come to him saying that they prophesied, cast out demons, and did mighty works in his name and he will tell them that he never knew them. Which means that prophesying, casting out demons, and doing mighty works in the name on Jesus is not the "will of my Father" (at least not solely) even to the point where Jesus calls them "workers of lawlessness". And that scares me because I can think of people close to me that might say something like that that to Jesus when they see him face-to-face. It seems utterly critical to figure out what the will of the Father is.

So what is the will of the Father? Leave your thoughts in the comment section below.
