7:21-29 Christ here shows that it will not be enough to own him for our Master, only in word and tongue. It is necessary to our happiness that we believe in Christ, that we repent of sin, that we live a holy life, that we love one another. This is his will, even our sanctification. Let us take heed of resting in outward privileges and doings, lest we deceive ourselves, and perish eternally, as multitudes do, with a lie in our right hand. Let every one that names the name of Christ, depart from all sin. There are others, whose religion rests in bare hearing, and it goes no further; their heads are filled with empty notions. These two sorts of hearers are represented as two builders. This parable teaches us to hear and do the sayings of the Lord Jesus: some may seem hard to flesh and blood, but they must be done. Christ is laid for a foundation, and every thing besides Christ is sand. Some build their hopes upon worldly prosperity; others upon an outward profession of religion. Upon these they venture; but they are all sand, too weak to bear such a fabric as our hopes of heaven. There is a storm coming that will try every man's work. When God takes away the soul, where is the hope of the hypocrite? The house fell in the storm, when the builder had most need of it, and expected it would be a shelter to him. It fell when it was too late to build another. May the Lord make us wise builders for eternity. Then nothing shall separate us from the love of Christ Jesus. The multitudes were astonished at the wisdom and power of Christ's doctrine. And this sermon, ever so often read over, is always new. Every word proves its Author to be Divine. Let us be more and more decided and earnest, making some one or other of these blessednesses and Christian graces the main subject of our thoughts, even for weeks together. Let us not rest in general and confused desires after them, whereby we grasp at all, but catch nothing.And the rain descended, and the floods came,.... Such builders, and such a building, cannot stand against the violent rain of Satan's temptations, the floods of the world's persecutions, the stream and rapid torrent of their own heart's lusts, nor the blowing winds of heresy and false doctrine, and much less the storms of divine wrath and vengeance. They are in a most dangerous condition; they cannot support themselves; they must fall, and great will be their fall; their destruction is inevitable, their ruin is irrecoverable. The Jews make use of some similes, which are pretty much like these of Christ's.

"R. Eliezer ben Azariah used to say (z), he whose wisdom is greater than his works, to what is he like? to a tree, whose branches are many, and its roots few, "and the wind comes", and roots it up, and overturns it; as it is said, Jeremiah 17:6 but he whose works are greater than his wisdom, to what is he like? to a tree, whose branches are few, and its roots many, "against which, if all the winds in the world were to come and blow", they could not move it out of its place: as it is said, Jeremiah 17:8.''

Again (a),

"Elisha ben Abuijah used to say, a man who hath good works, and learns the law much, to what is he like? to a man that "builds with stones below", and afterwards with bricks; and though , "many waters come", and stand at their side, they cannot remove them out of their place; but a man who hath no good works, and learns the law, to what is he like? to a man that "builds with bricks first", and afterwards with stones; and though few waters come, they immediately overturn them.''

The same used to say,

"a man who hath good works, and learns the law much, to what is he like? to mortar spread upon bricks; and though , "the rains descend upon it", they cannot remove it out of its place: a man that hath no good works, and learns the law much, to what is he like? to mortar thrown upon bricks; and though but a small rain descends upon it, it is immediately dissolved, and "falls".''
