Hence the apostle says, "If any man sin, we have"--what? The blood? Nay, but "an Advocate with the Father, Jesus Christ the righteous." The blood has done its work, and is ever before God according to its full value in His sight. Its efficacy is ever the same. But we have sinned; it may be only in thought; but even that thought is quite enough to interrupt our communion. Here is where advocacy comes in. If it were not that Jesus Christ is ever acting for us in the sanctuary above, our faith would most assuredly fail in moments in the which we have in any measure yielded to the voice of our sinful nature. Thus it was with Peter in that terrible hour of his temptation and fall: "Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat: but I have prayed for thee, that thy faith fail not: and when thou art converted (or restored), strengthen thy brethren" (Luke xxii. 21, 32). Let the reader note this. "I have prayed for thee, that"--What? Was it that he might not fail? Nay, but that, having failed, his faith might not give way. Had Christ not prayed for his poor, feeble servant, he would have gone from bad to worse, and from worse to worst. But the intercession of Christ procured for Peter the grace of true repentance, self-judgment and bitter sorrow for his sin, and finally complete restoration of his heart and conscience, so that the current of his communion--interrupted by sin, but restored by advocacy--might flow on as before. Thus it is with us when, through lack of that holy vigilance which we should ever exercise, we commit sin: Jesus goes to the Father for us. He prays for us; and it is through the efficacy of His priestly intercession that we are convicted and brought to self-judgment, confession, and restoration. All is founded on the advocacy, and the advocacy is founded on the atonement. And here it may be well to assert, in the clearest and strongest manner possible, that it is the sweet privilege of every believer not to commit sin. There is no necessity whatever why he should. "My little children," says the apostle, "these things write I unto you, that ye sin not." This is a most precious truth for every lover of holiness. _We need not sin._ Let us remember this. "Whosoever is born of God doth not commit [or, _practice_] sin; for His seed remaineth in him: and he cannot sin, because he is born of God" (1 John iii. 9). This is the divine idea of a Christian. Alas, we do not always realize it! but that does not, and cannot, touch the precious truth. The divine nature, the new man, the life of Christ in the believer, cannot possibly sin, and it is the privilege of every believer so to walk as that nothing but the life of Christ may be seen. The Holy Ghost dwells in the believer on the ground of redemption, in order to give effect to the desires of the new nature, so that the flesh may be as though it did not exist, and nothing but Christ be seen in the believer's life.
