New Defender's Study Bible Notes
7:22 wonderful works. It is remarkable that there are actually prophets and miracle workers who—perhaps sincerely, perhaps not—profess to be Christians but who instead are unsaved, deluded and even enabled to do “wonderful works” by Satan in order to lead people to follow a false Christ.
7:23 I never knew you. These false prophets are not people who once were saved and then became apostates. Christ never knew them!
7:23 work iniquity. The word “iniquity” here means “lawlessness.” Thus false prophets reject God’s law—i.e., His Word—in favor of their own philosophy or complex of experiences, and thus cannot do His will (Matthew 7:21, 26).
