Besides, there are many sins committed by us, dropping from us, and that pollute us, that we are not at all aware of; how then should we know that love of Christ by which we are delivered from them? Lord, "who can understand his errors?" said David (Psa 19:12). Consequently, who can understand the love that saves him from them? moreover, he that knows the love of Christ to the full, must also know to the full that wrath and anger of God, that like hell itself, burneth against sinners for the sake of sin: but this knows none. Lord, "who knoweth the power of thine anger?" said Moses (Psa 90:11). Therefore none knows this love of Christ to the full. The nature of sin is to get into our good, to mix itself with our good, to lie lurking many times under the formality and shew of good; and that so close, so cunningly, and invisibly, that the party concerned, embraces it for virtue, and knows not otherwise to do; and yet from this he is saved by the love of Christ; and therefore, as was hinted but now, if a man doth not know the nature of his wound, how should he know the nature and excellency of the balsam that hath cured him of his wound.
2. There are the due aggravations that belong to sin, which men are unacquainted with; it was one of the great things that the prophets were concerned with from God towards the people, (as to shew them their sins, so) to shew them what aggravations did belong thereto (Jer 2, Jer 3, Eze 16).
There are sins against light, sins against knowledge, sins against love, sins against learning, sins against threatenings, sins against promises, vows and resolutions, sins against experience, sins against examples of anger, and sins that have great, and high, and strange aggravations attending of them; the which we are ignorant of, though not altogether, yet in too great a measure. Now if these things be so, how can the love that saveth us from them be known or understood to the full?
Alas! our ignorance of these things is manifest by our unwillingness to abide affliction, by our secret murmuring under the hand of God; by our wondering why we are so chastised as we are, by our thinking long that the affliction is no sooner removed.
Or, if our ignorance of the vileness of our actions is not manifest this way, yet it is in our lightness under our guilt, our slight thoughts of our doings, our slovenly doing of duties, and asking of forgiveness after some evil or unbecoming actions. 'Tis to no boot to be particular, the whole course of our lives doth too fully make it manifest, that we are wonderful short in knowing both the nature, and also the aggravations of our sins: and how then should we know that love of Christ in its full dimensions, by which we are saved and delivered therefrom?
3. Who knows the utmost tendencies of sin? I mean, what the least sin driveth at, and what it would unavoidably run the sinner into. There is not a plague, a judgment, an affliction, an evil under heaven, that the least of our transgressions has not called for at the hands of the great God! nay, the least sin calleth for all the distresses that are under heaven, to fall upon the soul and body of the sinner at once. This is plain, for that the least sin deserveth hell; which is worse than all the plagues that are on earth. But I say, who understandeth this? And I say again, if one sin, the least sin deserveth all these things, what thinkest thou do all thy sins deserve? how many judgments! how many plagues! how many lashes with God's iron whip dost thou deserve? besides there is hell itself, the place itself, the fire itself, the nature of the torments, and the durableness of them, who can understand?
But this is not all, the tendencies of thy sins are to kill others. Men, good men little think how many of their neighbours one of their sins may kill. As, how many good men and good women do unawares, through their uncircumspectness, drive their own children down into the deep? (Psa 106:6,7) We will easily count them very hardhearted sinners, that used to offer their children in sacrifice to devils; when 'tis easy to do worse ourselves: they did but kill the body, but we body and soul in hell, if we have not a care.
Do we know how our sins provoke God? how they grieve the Holy Ghost? how they weaken our graces? how they spoil our prayers? how they weaken faith? how they tempt Christ to be ashamed of us? and how they hold back good from us? And if we know not every one of all these things to the full, how shall we know to the full the love of Christ which saveth us from them all?
4. Again, But who has the perfect knowledge of all these things? I will grant that some good souls may have waded a great way in some one, or more of them; but I know that there is not any that thoroughly know them all. And yet the love of Christ doth save us from all, notwithstanding all the vileness and soul-damning virtue12 that is in them. Alas! how short are we of the knowledge of ourselves, and of what is in us. How many are there that do not know that man consisteth of a body made of dust, and of an immortal soul? Yea, and how many be there of those that confess it, that know not the constitution of either. I will add, how many are there that profess themselves to be students of those two parts of man, that have oftentimes proved themselves to be but fools as to both? and I will conclude that there is not a man under heaven that knoweth it all together: For man is "fearfully and wonderfully made" (Psa 139:14): nor can the manner of the union of these two parts be perfectly found out. How much more then must we needs be at loss as to the fullness of the knowledge of the love of Christ? But,
Reason Third, He that altogether knoweth the love of Christ, must, precedent to that, know not only all the wiles of the devil; but also all the plottings, contrivings and designs and attempts of that wicked one; yea, he must know, all the times that he hath been with God, together with all the motions that he has made that he might have leave to fall upon us, as upon Job and Peter, to try if he might swallow us up (Job 1 and 2, Luke 22:31). But who knows all this? no man, no angel. For, if the heart of man be so deep, that none, by all his actions, save God, can tell the utmost secrets that are therein; how should the heart of angels, which in all likelihood are deeper, be found out by any mortal man. And yet this must be found out before we can find out the utmost of the love of Christ to us. I conclude therefore from all these things, that the love of Christ passeth knowledge: or that by no means, the bottom, the utmost bounds thereof can be understood.
