Few passages are more sobering than Matthew 7:21–23. Jesus warns that some will call Him “Lord, Lord,” point to their religious works, and yet hear Him say:
“I never knew you: depart from me, ye that work iniquity.” — Matthew 7:23
Many use this passage to frighten believers into thinking salvation can be lost. But Jesus did not say, “I knew you once.” He said, “I never knew you.” That distinction matters.
Matthew 7 concludes the Sermon on the Mount with several contrasts: the narrow way and the broad way, good trees and corrupt trees, wise builders and foolish builders.
The issue is not a believer losing everlasting life. The issue is false confidence. Jesus is exposing those who appear religious, speak religiously, and even claim impressive works, while never truly belonging to Him.
The people in this passage speak respectfully. They call Jesus “Lord.” But their appeal is not to His promise, His blood, or His finished work.
They say:
“Have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?” — Matthew 7:22
Their confidence is in what they have done. They point to ministry, miracles, and wonderful works. That is the opposite of resting in Christ alone.
Jesus does not say, “I knew you, but then you lost salvation.”
He does not say, “You were once Mine, but now you are not.”
He says:
“I never knew you.”
That single word never is crucial. These people were never known by Christ as His own.
In John 10, Jesus says of His sheep:
“My sheep hear my voice, and I know them, and they follow me.” — John 10:27
Then He promises:
“And I give unto them eternal life; and they shall never perish...” — John 10:28
Those whom Christ knows are secure. They shall never perish. Matthew 7 describes people He never knew, not sheep He knew and later lost. See John 10:28–29 Explained.
Notice what is missing from their defense.
They do not say, “Lord, we believed Your promise.”
They do not say, “You gave us everlasting life.”
They do not say, “You said the believer shall not come into condemnation.”
Instead, they point to works. This makes Matthew 7 an important companion to Does James 2 Teach Salvation by Works?, The Rich Young Ruler, and Romans 4:5 Explained.
Jesus calls them workers of iniquity. Their religious activity did not make them righteous before God.
Iniquity can dress itself in religious language. It can even boast in impressive works. But if a person is trusting those works instead of Christ, that confidence cannot save.
When Jesus explains how to receive eternal life, His words are simple:
“Verily, verily, I say unto you, He that believeth on me hath everlasting life.” — John 6:47
He also says:
“He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation...” — John 5:24
Those promises are not based on prophesying, casting out devils, or doing wonderful works. They are based on believing Christ. See John 6:47 Explained and John 5:24 Explained.
Matthew 7 is a real warning, but not against losing eternal life. It warns against religious profession without saving faith in Christ.
These people had words. They had works. They had religious confidence. But they did not have Christ.
That is why this passage belongs alongside Can Salvation Be Lost?, Does Hebrews 6 Teach You Can Lose Salvation?, What Does Hebrews 10:26 Really Mean?, and What Does “Endure to the End” Mean?.
Many sincere believers tremble over Matthew 7 because they look at themselves and wonder if they have done enough.
But the people Jesus rejects are doing the opposite of faith. They are presenting their works as evidence that He should receive them.
The gospel points away from our record and toward Christ. The question is not, “Have I done enough wonderful works?” The question is, “Am I trusting Jesus Christ and His promise of everlasting life?”
Matthew 7:21–23 does not teach that a believer can lose salvation.
Jesus did not say, “I knew you once.” He said, “I never knew you.”
The passage warns against false religious confidence, especially confidence in works. Those who receive everlasting life are not those who boast in what they have done, but those who believe in Christ.
The believer’s assurance rests in the promise of Jesus:
“Him that cometh to me I will in no wise cast out.” — John 6:37
