Throughout it is not mere acts the Lord demands, but state; the spiritual condition suitable for the kingdom of the heavens. As in the verses immediately preceding the Lord insists on a spirit of lowly grace, going immeasurably beyond Thou shalt not kill, so now on a purity as far beyond the non-commission of adultery.
It is plain also that here, as everywhere in the so-called Sermon on the Mount, it is not the grace which saves the lost sinner who repents and believes the gospel. The state of soul that befits entrance into the kingdom of the heavens exclusively occupies the Lord: He is teaching the disciples what suited the Father's name which He made known to them. All that He laid down therefore manifestly presupposes that one is born of God, as the essential requisite for His kingdom, not acts merely if they could be good, but renewal of heart. Christ Himself was the blessed pattern of perfection.
" Ye heard that it was said, Thou shalt not commit adultery; but I say unto you that every one that looketh at a woman to lust after her committed adultery with her already in his heart. And if thy right eye stumbleth (or, ensnareth) thee, pluck out and cast it from thee; for it profiteth thee that one of thy members perish, and not thy whole body be cast into hell. And if thy right hand stumbleth thee, cut off and cast it from thee; for it profiteth thee, that one of thy members perish, and not thy whole body be cast into hell."
Violence and corruption are the sad characteristics of man's fallen estate. We see them marked in the antediluvian world, at least as the general signs of a ruined state, whatever the specific evil which aroused divine indignation and unsparing judgment. Throughout man's history as traced in the Bible, and particularly in the favored circle of Israel under the law, they are ever before us. Christ came, and grace and truth through Him, and redemption through His blood, everlasting redemption, to say nothing now of heavenly counsels made good in His person and place, and communications to the Christian and to the church. But man is essentially unchanged, and even avails himself of grace to become the worse. " Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set to do evil." " But when thy judgments are in the earth," says the prophet, " the inhabitants of the world learn righteousness." Showing favor to the wicked, who believe not, emboldens them to persevere. And as the Jew was no exception who dealt wrongfully in the land of uprightness and would not behold the majesty of Jehovah, so will the Gentile reject the gospel to his perdition, and be cut off irretrievably. The time also hastens.
But as of old, so now are the faithful men, of whom the world is not worthy, who lived and suffered as seeing Him who is invisible. And the Lord did not lower the standard but raised it, clearing it of letter and of all accretions or diminutions. He has the godly remnant in view, still Jewish as He spoke, who not only entered the kingdom, but had higher relations intimated as His rejection set in, till His session at God's right hand and mission of the Spirit gave all necessary to reveal and make good in the saints what had been ever hidden heretofore.
As violence then was judged and excluded in any shape for the disciples, so was impurity. The avoidance of the extreme act might satisfy a Pharisee or Scribe; but the Lord could not dispense with anything short of truth in the inward parts. To look at a woman lustfully was to commit adultery with her already in his heart; and it is not the outside only that God regards but the heart above all. It is only a new nature that delights in holiness; and he who has it by grace answers to the will of God his Father; and abhors himself if he slip even into a wrong look, as unworthy of his calling and hateful to Him who loves him.
But the Lord follows up His stringent condemnation by the call to deal promptly and unreservedly with anything that acted as an incentive. Therefore He specifies that which is part of ourselves, and when rightly used of the greatest value. Not even the right eye, or the right foot, can be allowed in presence of His displeasure which the saint fears, because he is a believer and God's child; as the Lord said elsewhere, " Be not afraid of those that kill the body, and after that have no more that they can do. But I will tell you whom ye shall fear. Fear him who, after he hath killed the body, hath power to cast into hell; yea, I say to you, Fear him." It is not the highest motive, but it is an imperative and most solemn and urgent appeal.
Therefore says He now, " And if thy right eye stumbleth thee, pluck out and cast it from thee; for it profiteth thee that one of thy members perish, and not thy whole body be cast into hell. And if thy right hand stumbleth thee, cut off and cast it from thee; for it profiteth thee, that one of thy members perish, and not thy whole body be cast into hell." The right eye and the right hand present forcibly the mortifying of our members that are on the earth, to hinder sin against God. At all cost must the believer deny self; as we find elsewhere he must hate father, mother, wife, children, brethren, sisters, yea and his own life also, or he cannot be Christ's disciple.
O my fellow-sinner, you know that this is wholly beyond you. You do not, will not, make any such sacrifices. Nothing but Christ, the new life, can so feel and act; and you have only your depraved life of sin and self. Are you then to despair? Yes, despair of yourself. You are truly lost, as the Lord says. But He came to seek and to save the lost. Tell God of your guilt and ruin, but plead the name of Jesus whom He has sent. He is a present and everlasting Savior. Doubt not, but believe what God declares of His Son. Life in Him answers to the appeal of Jesus, when you rest on His redemption; and the Holy Spirit will strengthen you accordingly.
