The Blessings of Obedience

12 It shall happen, because you listen to these ordinances, and keep and do them, that Yahweh your God will keep with you the covenant and the loving kindness which he swore to your fathers: 13 and he will love you, and bless you, and multiply you; he will also bless the fruit of your body and the fruit of your ground, your grain and your new wine and your oil, the increase of your livestock and the young of your flock, in the land which he swore to your fathers to give you. 14 You shall be blessed above all peoples: there shall not be male or female barren among you, or among your livestock. 15 Yahweh will take away from you all sickness; and none of the evil diseases of Egypt, which you know, he will put on you, but will lay them on all those who hate you. 16 You shall consume all the peoples whom Yahweh your God shall deliver to you; your eye shall not pity them: neither shall you serve their gods; for that will be a snare to you.

Commentary on Deuteronomy 7:12-26

(Read Deuteronomy 7:12-26)

We are in danger of having fellowship with the works of darkness if we take pleasure in fellowship with those who do such works. Whatever brings us into a snare, brings us under a curse. Let us be constant to our duty, and we cannot question the constancy of God's mercy. Diseases are God's servants; they go where he sends them, and do what he bids them. It is therefore good for the health of our bodies, thoroughly to mortify the sin of our souls; which is our rule of duty. Yet sin is never totally destroyed in this world; and it actually prevails in us much more than it would do, if we were watchful and diligent. In all this the Lord acts according to the counsel of his own will; but that counsel being hid from us, forms no excuse for our sloth and negligence, of which it is in no degree the cause. We must not think, that because the deliverance of the church, and the destruction of the enemies of the soul, are not done immediately, therefore they will never be done. God will do his own work in his own method and time; and we may be sure that they are always the best. Thus corruption is driven out of the hearts of believers by little and little. The work of sanctification is carried on gradually; but at length there will be a complete victory. Pride, security, and other sins that are common effects of prosperity, are enemies more dangerous than beasts of the field, and more apt to increase upon us.
