The Lord Jesus winds up the Sermon on the Mount by a passage of heart-piercing application. He turns from false prophets to false professors, from unsound teachers to unsound hearers. Here is a word for all. May we have grace to apply it to our own hearts!

The first lesson here is the uselessness of a mere outward profession of Christianity. Not everyone that saith “Lord, Lord” shall enter the kingdom of heaven. Not all that profess and call themselves Christians shall be saved.

In this part of the Sermon on the Mount our Lord begins to draw His discourse to a conclusion. The lessons He here enforces on our notice, are broad, general, and full of the deepest wisdom. Let us mark them in succession.

He lays down a general principle for our guidance in all doubtful questions between man and man.

We are “to do to others as we would have others do to us.” We are not to deal with others as others deal with us: this is mere selfishness and heathenism. We are to deal with others as we would like others to deal with us: this is real Christianity.

The first portion of these verses is one of those passages of Scripture, which we must be careful not to strain beyond its proper meaning. It is frequently abused and misapplied by the enemies of true religion. It is possible to press the words of the Bible so far that they yield not medicine, but poison.

When our Lord says, “Judge not”, He does not mean that it is wrong, under any circumstances, to pass an unfavourable judgment on the conduct and opinions of others. We ought to have decided opinions: we are to “prove all things”; we are to “try the spirits.’’ (1 Thess. 5:21; 1 John 4:1) Nor yet does He mean that it is wrong to reprove the sins and faults of others until we are perfect and faultless ourselves. Such an interpretation would contradict other parts of Scripture: it would make it impossible to condemn error and false doctrine; it would debar any one from attempting the office of a minister or a judge. The earth would be “given into the hands of the wicked“ (Job 9:24): heresy would flourish: wrong-doing would abound.
