3:13-18 Among the Jews at this time, some plainly discovered themselves to be children of the wicked one. The yoke of Christ is easy. But those who work wickedness, tempt God by presumptuous sins. Judge of things as they will appear when the doom of these proud sinners comes to be executed. Those that feared the Lord, spake kindly, for preserving and promoting mutual love, when sin thus abounded. They spake one to another, in the language of those that fear the Lord, and think on his name. As evil communications corrupt good minds and manners, so good communications confirm them. A book of remembrance was written before God. He will take care that his children perish not with those that believe not. They shall be vessels of mercy and honour, when the rest are made vessels of wrath and dishonour. The saints are God's jewels; they are dear to him. He will preserve them as his jewels, when the earth is burned up like dross. Those who now own God for theirs, he will then own for his. It is our duty to serve God with the disposition of children; and he will not have his children trained up in idleness; they must do him service from a principle of love. Even God's children stand in need of sparing mercy. All are righteous or wicked, such as serve God, or such as serve him not: all are going to heaven or to hell. We are often deceived in our opinions concerning both the one and the other; but at the bar of Christ, every man's character will be known. As to ourselves, we have need to think among which we shall have our lot; and, as to others, we must judge nothing before the time. But in the end all the world will confess that those alone were wise and happy, who served the Lord and trusted in Him.

16. "Then," when the ungodly utter such blasphemies against God, the godly hold mutual converse, defending God's righteous dealings against those blasphemers (Heb 3:13). The "often" of English Version is not in the Hebrew. There has been always in the darkest times a remnant that feared God (1Ki 19:18; Ro 11:4).

feared the Lord—reverential and loving fear, not slavish terror. When the fire of religion burns low, true believers should draw the nearer together, to keep the holy flame alive. Coals separated soon go out.

book of remembrance … for them—for their advantage, against the day when those found faithful among the faithless shall receive their final reward. The kings of Persia kept a record of those who had rendered services to the king, that they might be suitably rewarded (Es 6:1, 2; compare Es 2:23; Ezr 4:15; Ps 56:8; Isa 65:6; Da 7:10; Re 20:12). Calvin makes the fearers of God to be those awakened from among the ungodly mass (before described) to true repentance; the writing of the book thus will imply that some were reclaimable among the blasphemers, and that the godly should be assured that, though no hope appeared, there would be a door of penitence opened for them before God. But there is nothing in the context to support this view.
