Be not judges of your own condition, but let Christ judge. You are invited to take the comfort of this gospel truth, that “there is forgiveness with God.” You say, not for you. So said Jacob, “My way is hid from the LORD,” Isaiah 40:27; and Zion said so too, Isaiah 44:14, “The LORD hath forsaken me, and my Lord hath forgotten me.” But did they make a right judgment of themselves? We find in those places God was otherwise minded. This false judgment, made by souls in their entanglements, of their own condition, is oft times a most unconquerable hindrance unto the bettering of it. They fill themselves with thoughts of their own about it, and on them they dwell, instead of looking out for a remedy. Misgiving thoughts of their distempers are commonly a great part of some men’s sickness. Many diseases are apt to cloud the thoughts, and to cause misapprehensions concerning their own nature and danger. And these delusions are a real part of the person’s sickness. Nature is no less impaired and weakened by them, the efficacy of remedies no less obstructed, than by any other real distemper. In such cases we persuade men to acquiesce in the judgment of their skillful physician; not always to be wasting themselves in and by their own tainted imaginations, and so despond upon their own mistakes, but to rest in what is informed them by him who is acquainted with the causes and tendency of their indisposition better than themselves. It is ofttimes one part of the soul’s depths to have false apprehensions of its condition. Sin is a madness (Ecclesiastes 9:3); so far as anyone is under the power of it, he is under the power of madness. Madness doth not sooner nor more effectually discover itself in any way or any thing than in possessing them in whom it is with strange conceits and apprehensions of themselves. So doth this madness of sin, according to its degrees and prevalency. Hence some cry, “Peace, peace,” when “sudden destruction is at hand” (1 Thessalonians 5:3). It is that madness, under whose power they are, which gives them such groundless imaginations of themselves and their own condition. And some say they are lost forever, when God is with them.
Do you, then, your duty and let Christ judge of your state. Your concernment is too great to make a reasonable demand to commit the judgment of your condition to any other. When eternal welfare or woe are at the stake, for a man to renounce his own thoughts, to give up himself implicitly to the judgment of men and liars like himself, is stupidity. But there is no danger of being deceived by the sentence of Christ. The truth is, whether we will or no, he will judge; and according as he determines, so shall things be found at the last day, (John 5:22) “The Father judgeth no man” (that is,immediately and in his own person), “but hath committed all judgment unto the Son.” All judgment that respects eternity, whether it be to be passed in this world or in that to come, is committed unto him. Accordingly in that place he judgeth both of things and persons. Things he determines upon, verse 24, “He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.” Let me say what they please, this sentence shall stand; faith and eternal life are inseparably conjoined. And so of persons, verse 38, “Ye have not” (saith he to the Pharisees, who were much otherwise minded) “the word of God abiding in you.”
Take not, then, the office and prerogative of Christ out of his hand, by making a judgment, upon your own reasonings and conclusions and deductions, of your estate and condition.
