3. They plead the unchangeableness of God's favour and the stability of his promise, notwithstanding the sins of his people and his displeasure against them for their sins: "Behold, thou hast many a time been wroth with us because we have sinned, and we have been under the tokens of thy wrath; but in those, those ways of thine, the ways of mercy in which we have remembered thee, in those is continuance," or "in those thou art ever" (his mercy endures for ever), "and therefore we shall at last be saved, though thou art wroth, and we have sinned." This agrees with the tenour of God's covenant, that, if we forsake the law, he will visit our transgression with a rod, but his loving kindness he will not utterly take away, his covenant he will not break (Ps. lxxxix. 30, &c.), and by this his people have been many a time saved from ruin when they were just upon the brink of it; see Ps. lxxviii. 38. And by this continuance of the covenant we hope to be saved, for its being an everlasting covenant is all our salvation. Though God has been angry with us for our sins, and justly, yet his anger has endured but for a moment and has been soon over; but in his favour is life, because in it is continuance; in the ways of his favour he proceeds and perseveres, and on that we depend for our salvation, see ch. liv. 7, 8. It is well for us that our hopes of salvation are built not upon any merit or sufficiency of our own (for in that there is no certainty, even Adam in innocency did not abide), but upon God's mercies and promises, for in those, we are sure, is continuance.
