John Trapp on Micah 7:19

Verſe 19. He will turne again, he will have compaſſion upon us] Here's the pith and power of faith, particularly applying promiſes to a mans ſelf. Say that ſin hath ſeparated betwixt us and our God, Eſay 59.2. and made him ſend us farre away into captivity: yet he will turn again and yern toward us, he will turn again our captivity as the ſtreams in the South. His compaſſions are more then fatherly, Pſal. 103.13. motherly, Eſay 49.15. brotherly, Heb. 2.12. This the Church knows, and therefore cries after him,Cant. 8.14. Make haſt my beloved; and be thou like to a Roe, or to a young Hart, which when it fleeth, looketh behind it, ſaith the Chaldee Paraphraſt there. And this that he will do, ſhe is bold to beleeve. He will, he will, and that to us, ſaith the Prophet here. Lo this is that work of faith, to wrap it ſelf in the promiſes, as made to us in particular, 1 Tim. 1.15. and unleſſe faith be on this ſort actuated, it is, as to comfort, as good as no faith. Compare Mat. 8.26. with Mark. 4.40.

He will ſubdue our iniquities] By force and violence (as the word ſignifieth) ſubjugabit, peſſundabit, conculcabit. Sin is ſturdy, and will rebell, where it cannot reigne. It hath a ſtrong heart, and will not eaſily yeeld. But yeeld it ſhall, for God will ſubdue it. And this is a further favour, (as every former is a pledge of a future) To pardon of ſinne, God will adde power againſt ſinne: to juſtification by Chriſts merit, ſanctification by his Spirit: he will let out the life-blood of ſin, and lay it adying at our feet: he will tread Satan with all his black train under our feet ſhortly, Rom. 16.20. He will not onely turn us againe, but turne his hand upon us, and purely purge away our droſſe, and take away all our tinne, Eſay 1.25. In fine, hee will ſo mortifie the deeds of the body by his Spirit, that ſinne ſhall not have dominion over us, Rom. 6.14. ſhall not play Rex in us: the traveller ſhall not become the man of the houſe, as Nathans parable ſpeaketh.

And thou wilt caſt all their ſinnes into the bottom of the ſea] Where-hence they ſhall never be boyed up again. This, the Prophet by an inſinuating Apoſtrophe, turneth himſelf to God, and ſpeaketh with much confidence. Such is the nature of true faith, ſc. to grow upon God, and, as I may ſo ſay, to encroach: as Moſes did, Exod. 33.12, 13, &c. to chap. 34.10. and as David did, 1 Chron. 17.23. &c. See how he improves Gods promiſe, and works upon it, ver. 24, 25. he goes it over again, and yet ſtill encroacheth: and the effect was good, chap. 18. We hinder our ſelves of much happineſſe by a ſinfull ſhamefacedneſſe. Let us come boldly to the throne of grace;Heb. 4. ult. ſo ſhall we ſee our ſins, as Iſrael did the Egyptians dead on the ſhore.
