"Grace and the wisdom of God" - John Bunyan

“And he showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.” - Revelation 22:1

“When we read that out of the throne proceeds a river of grace; when we read this proceedeth out of the throne of God, it is as much as to say the wise God, who most perfectly knoweth all ways, counteth, in his wisdom, that to save men by grace is the best, most safe, and sure way: "Therefore it is of faith, that it might be by grace, to the end the promise might be sure to all the seed" (Rom 4:16). And, again, forgiveness is according to the riches of his grace, wherein he hath abounded toward us in all wisdom and prudence (Eph 1:7,8).
Wherefore, to set grace upon the throne, to let grace proceed out of the throne as a river, is by the wise God, the only wise God, counted the best way, the safest way, the way that doth best suit the condition of a sinful man, and that tends most to the utter disappointment of the devil, and death, and hell.
Grace can justify freely, when it will, who it will, from what it will. Grace can continue to pardon, favour, and save from falls, in falls, out of falls. Grace can comfort, relieve, and help those that have hurt themselves. And grace can bring the unworthy to glory. This the law cannot do, this man cannot do, this angels cannot do, this God cannot do, but only by the riches of his grace, through the redemption that is in Jesus Christ. Wherefore, seeing God has set grace on the throne, and ordered that it should proceed from this throne to the world; yea, seeing he has made it king, and granted to it, to it only, the authority and sovereignty of saving souls, he has magnified not only his love, but his wisdom and his prudence before the sons of men. This, then, is his great device, the master-piece of all his witty inventions; and, therefore, it is said, as was hinted before, in this thing he hath proceeded towards us in ALL wisdom and prudence (2 Sam 14:14; Prov 8:11,12).”
