“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.’
“Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.”
And when Jesus finished these sayings, the crowds were astonished at his teaching, for he was teaching them as one who had authority, and not as their scribes. Matthew 7:21-29
Jesus had just warned against those false prophets who do not speak the truth. But, what about those who may speak at least some of the truth, but live the lie? In this last section of the sermon He speaks to that issue.
In referring to those who say, “Lord, Lord,” Jesus speaks of some who will come, at the Last Day, feigning service to Him. Having spent their lives deceiving others (and perhaps themselves), they will now seek to deceive the final Judge of all mankind. Although they may say the right words, their fruit tells another story. And, it is by their fruit that they must be judged.
These people speak of prophesying, casting out demons, and doing mighty works in Jesus’ name. Yet, He says, they will not enter the kingdom. So, there must be more to doing God’s will than these things. It must be remembered that these are not the things about which Jesus talks in the sermon. It is as we do the things he does talk about – as we live that way – that we do the will of God and show ourselves to be true believers – true children of God.
How can Jesus say, “I never knew you?” As God, Jesus is omniscient. He knows all things. Therefore, this statement cannot mean that He was never aware of these people’s existence. He means that never for a moment did He acknowledge them as His own. Never did He know them in the intimate way in which He knows those who are His.
To further show the need to do the things of God, Jesus uses the story of two builders. Each of these men builds a house, and the houses appear to be very similar. The difference between the two is the foundation on which they build. In the story, the firm foundation represents the sound words of Jesus. His words offer the support we need for our lives. Without them, we cannot stand against the wind and storms of persecution and temptation. Without them, our foundation shifts, and we will fail to stand against the opposition of Satan and the world.
The crowds are said to have seen Jesus as one who had authority. John refers to Jesus as the Word of God (John 1:1-2). The writer to the Hebrews informs us that, in these last days, God has spoken to us through His Son (Hebrews 1:1-2). And, Paul tells Timothy that all Scripture is breathed out by God (2 Timothy 3:16). The words of the Old Testament which Jesus quoted and explained were His own words. As the Author of those great biblical truths, He had the authority to teach on them and to explain them.
