1. What were the terms on which God would show favour to them. It is always provided that they will diligently learn the ways of my people, that is, in general, the ways that they walk in when they conduct themselves as my people (not the crooked ways into which they have turned aside), the ways which my people are directed to take. Note, (1.) There are good ways that are peculiarly the ways of God's people, which however they may differ in the choice of their paths, they are all agreed to walk in. The ways of holiness and heavenly-mindedness, of love and peaceableness, the ways of prayer and sabbath-sanctification, and diligent attendance on instituted ordinances—these, and the like, are the ways of God's people. (2.) Those that would have their lot with God's people, and their last end like theirs, must learn their ways and walk in them, must observe the rule they walk by and conform to that rule they walk by and conform to that rule and go forth by those footsteps. By an intimate conversation with God's people they must learn to do as they do. (3.) It is impossible to learn the ways of God's people as they should be learnt, without a great deal of care and pains. We must diligently observe these ways and diligently obliges ourselves to walk in them, must look diligently (Heb. xii. 15), and work diligently, Luke xiii. 24. In particular, they must learn to give honour to God's name by making all their solemn appeals to him. They must learn to say, The Lord liveth (to own him, to adore him, and to abide by his judgment), as they taught my people to swear by Baal. It was bad enough that they did themselves swear by Baal, worse that they taught God's own people, who had been better taught; and yet, if they will at length reform, they shall be accepted. Observe, [1.] We must not despair of the conversion of the worst; no, not of those who have been instrumental to pervert and debauch others; even they may be brought to repentance, and, if they be, shall find mercy. [2.] Those whom we have been industrious to draw to that which is evil, when God opens their eyes and ours, we should be as industrious to follow in that which is good. It will be a holy revenge upon ourselves to become pupils to those in the way of duty to whom we have been tutors in the was of sin. [3.] The conversion of the deceived may prove a happy occasion of the conversion even of the deceivers. Thus those who fall together into the ditch are sometimes plucked together out of it.
