It sometimes so falleth out, that the very promise we have thought could not reach us to comfort us by any means, has at another time swallowed us up with joy unspeakable: Christ the true prophet has the right understanding of the word as an Advocate, has pleaded it before God against Satan; and having overcome him at the common law, he has sent to let us know it by his good Spirit, to our comfort and the confusion of our enemies. XVIII. CHRISTIAN GRACES. FAITH. FAITH! Peter saith, faith, in the very trial of it, is much more precious than gold that perisheth. If so, what is the worth or value that is in the grace itself? Faith is so great an artist in arguing and reasoning with the soul, that it will bring over the hardest heart that it hath to deal with. It will bring to my remembrance at once, both my vileness against God, and his goodness towards me; it will show me, that though I deserve not to breathe in the air, yet God will have me an heir of glory. Faith is the mother-grace, the root-grace, the grace that has all others in the bowels of it, and that from which all others flow. Faith will suck sweetness out of God's rod; but unbelief can find no comfort in his greatest mercies. Faith makes great burdens light; but unbelief maketh light ones intolerably heavy. Faith helpeth us when we are down; but unbelief throws us down when we are up. Unbelief may be called the WHITE DEVIL; for it often-times, in its mischievous doing in the soul, shows as if it was an angel of light; yea, it acteth like a counsellor of heaven. It is that sin above all others that most suiteth the wisdom of our flesh. The wisdom of our flesh thinks it prudent to question a while, to stand back a while, to hearken to both sides a while; and not to be rash, sudden, or unadvised in too bold a presuming upon Jesus Christ. There is nothing like faith to help at a pinch; faith dissolves doubts, as the sun drives away the mists. And that you may not be put out, know your time of believing is always. There are times when some graces may be out of use; but there is no time wherein faith can be said to be so. Faith is the eye, the mouth, the hand, and one of these is of use all day long. Faith is to see, to receive, to work, or to eat; and a Christian should be seeing, or receiving, or working, or feeding, all day long. Let it rain, let it blow, let it thunder, let it lighten, a Christian must still believe. "Above all, taking the shield of faith, wherewith you shall be able to quench all the fiery darts of the wicked:" to quench them, though they come from him as kindled with the very fire of hell. None knows, save he that feels it, how burning hot the fiery darts of Satan are; and how, when darted, they kindle upon our flesh and unbelief; neither can any know the power and worth of faith to quench them, but he that hath it and hath power to act it. There are three things in faith, that directly tend to make a man depart from iniquity.
