John Trapp on Psalms 31:19

Verſ. 19. Oh how great is thy goodneſſe] The Prophet venteth himſelf by way of exclamation, as finding it unſpeakable; fitter to be beleeved, than poſſible to be diſcourſed; words are too weak to utter it. What ſhall we ſay to theſe things? quoth that great Apoſtle, Rom. 8.31.

Which thon haſt laid up] Heb. Hidden. Beſides that good which God worketh openly for his before the ſons of men, a great part of his wonderfull kindneſſe is hidden from the world, and in part alſo from themſelves, both in reſpect of the fountain, 1 Joh. 3.1, 2. Col. 3.3. the fullneſſe, 1 Cor. 2.9. and the inward ſealing up thereunto, 1 Cor. 2.11, 12. Rev. 2.17. Prov. 14.10.

For them that fear thee — that truſt in thee] For faith muſt be actuated; and when we have ſuch a precious promiſe as this, we muſt ſuck and be ſatisfied, Iſa. 66.11. put on to get the goodneſſe of God to work, which is done by beleeving. Catch hold, as David did, 1 Chron. 17.23, 24, 25, 26. and make the utmoſt of Gods loving kindneſſe laid up in a promiſe; preſs it, and oppreſſe it, till the goodneſſe be expreſſed out of theſe breaſts of conſolation.
