Verse 1-4 — "Lord, teach us to pray," is a good prayer, and a very needful one, for Jesus Christ only can teach us, by his word and Spirit, how to pray. Lord, teach me what it is to pray; Lord, stir up and quicken me to the duty; Lord, direct me what to pray for; teach me what I should say. Christ taught them a prayer, much the same that he had given before in his sermon upon the mount. There are some differences in the words of the Lord's prayer in Matthew and in Luke, but they are of no moment. Let us in our requests, both for others and for ourselves, come to our heavenly Father, confiding in his power and goodness.
Verse 5-13 — Christ encourages fervency and constancy in prayer. We must come for what we need, as a man does to his neighbour or friend, who is kind to him. We must come for bread; for that which is needful. If God does not answer our prayers speedily, yet he will in due time, if we continue to pray. Observe what to pray for; we must ask for the Holy Spirit, not only as necessary in order to our praying well, but as all spiritual blessings are included in that one. For by the influences of the Holy Spirit we are brought to know God and ourselves, to repent, believe in, and love Christ, and so are made comfortable in this world, and meet for happiness in the next. All these blessings our heavenly Father is more ready to bestow on every one that asks for them, than an indulgent parent is to give food to a hungry child. And this is the advantage of the prayer of faith, that it quiets and establishes the heart in God.
Verse 14-26 — Christ's thus casting out the devils, was really the destroying of their power. The heart of every unconverted sinner is the devil's palace, where he dwells, and where he rules. There is a kind of peace in the heart of an unconverted soul, while the devil, as a strong man armed, keeps it. The sinner is secure, has no doubt concerning the goodness of his state, nor any dread of the judgment to come. But observe the wonderful change made in conversion. The conversion of a soul to God, is Christ's victory over the devil and his power in that soul, restoring the soul to its liberty, and recovering his own interest in it and power over it. All the endowments of mind of body are now employed for Christ. Here is the condition of a hypocrite. The house is swept from common sins, by a forced confession, as Pharaoh's; by a feigned contrition, as Ahab's; or by a partial reformation, as Herod's. The house is swept, but it is not washed; the heart is not made holy. Sweeping takes off only the loose dirt, while the sin that besets the sinner, the beloved sin, is untouched. The house is garnished with common gifts and graces. It is not furnished with any true grace; it is all paint and varnish, not real nor lasting. It was never given up to Christ, nor dwelt in by the Spirit. Let us take heed of resting in that which a man may have, and yet come short of heaven. The wicked spirits enter in without any difficulty; they are welcomed, and they dwell there; there they work, there they rule. From such an awful state let all earnestly pray to be delivered.
Verse 27,28 — While the scribes and Pharisees despised and blasphemed the discourses of our Lord Jesus, this good woman admired them, and the wisdom and power with which he spake. Christ led the woman to a higher consideration. Though it is a great privilege to hear the word of God, yet those only are truly blessed, that is, blessed of the Lord, that hear it, keep it in memory, and keep to it as their way and rule.
Verse 29-36 — Christ promised that there should be one sign more given, even the sign of Jonah the prophet; which in Matthew is explained, as meaning the resurrection of Christ; and he warned them to improve this sign. But though Christ himself were the constant preacher in any congregation, and worked miracles daily among them, yet unless his grace humbled their hearts, they would not profit by his word. Let us not desire more evidence and fuller teaching than the Lord is pleased to afford us. We should pray without ceasing that our hearts and understandings may be opened, that we may profit by the light we enjoy. And especially take heed that the light which is in us be not darkness; for if our leading principles be wrong, our judgment and practice must become more so.
Verse 37-54 — We should all look to our hearts, that they may be cleansed and new-created; and while we attend to the great things of the law and of the gospel, we must not neglect the smallest matter God has appointed. When any wait to catch something out of our mouths, that they may insnare us, O Lord, give us thy prudence and thy patience, and disappoint their evil purposes. Furnish us with such meekness and patience that we may glory in reproaches, for Christ's sake, and that thy Holy Spirit may rest upon us.
