When we accept the Lord Jesus Christ as our Savior, the Spirit of God comes to live in our body. He contrasts this power with the power of demons, which is just as real!
V.2 He reminds them that they used to be under the power of these demons.
V.3 No one, speaking in the power of the Spirit of God says “curse on Jesus.” And in contrast, no one can say “Lord Jesus” unless in the power of the Holy Spirit. Did you ever notice that when people curse, they never say this? They may take His name in vain, but not in this way.
V.4-11 God gives different believers different powers. But please notice that one person does not receive several gifts. A man who assumes a place among believers where he has to use more than one or two gifts is plainly in an unscriptural position.
V.13 All believers are in the one body. This unity cannot be divided.
