Matthew 7:23

And they will I profess unto them, I never knew you: depart from me, ye that work iniquity.

In Matthew 7:22, above, "that day" obviously refers to the judgment; and in this verse Christ claims for himself the right to consign men to banishment from his holy presence. The entire tone and tenor of this sermon is predicated on the assumption that Christ is God. Language of the kind recorded here would be the utmost nonsense if this is not his claim. Biederwolf said, "A man who can read the New Testament and not see that Christ claims to be more than a man, can look all over the sky at high noon on a cloudless day and not see the sun."[10]

This verse contains, without doubt, one of the most terrible thoughts in the Scriptures. Many souls shall diligently serve God and do many mighty things in his name, only to discover at last that they have never really served him at all. This blessed warning from Christ should stop every man short and suddenly until he is sure beyond all possibility of deception that he is truly doing Christ's will. The final and climactic paragraph of the Sermon on the Mount lays down the true guidelines for souls truly desirous of knowing what is the will of God.
