'_Beloved! let us cleanse ourselves._' The cleansing is sometimes spoken of as the work of God (Acts xv. 9; 1 John i. 9); sometimes as that of Christ (John xv. 3; Eph. v. 26; Tit. ii. 14). Here we are commanded to cleanse ourselves. God does His work in us by the Holy Spirit; the Holy Spirit does His work by stirring us up and enabling us to do. The Spirit is the strength of the new life; in that strength we must set ourselves determinedly to cast out whatever is unclean. 'Come out, and be ye separate, and touch not the unclean thing.' It is not only the doing what is sinful, it is not only the willing of it, that the Christian must avoid, but even the touching it: the involuntary contact with it must be so unbearable as to force the cry, O wretched man that I am! and to lead on to the deliverance which the Spirit of the life of Christ does bring.
And how is this cleansing to be done? When Hezekiah called the priests to sanctify the temple that had been defiled, we read (2 Chron. xxix.), 'The priests went in unto the inner part of the house of the Lord to cleanse it, and brought out all the uncleanness that they found.' Only then could the sin-offering of atonement and the burnt-offering of consecration, with the thankofferings, be brought, and God's service be restored. Even thus must all that is unclean be looked out, and brought out, and utterly cast out. However deeply rooted the sin may appear, rooted in constitution and habit, we must cleanse ourselves of it if we would be holy. 'If we walk in the light, as He is in the light, the blood of Jesus Christ cleanseth from all sin.' As we bring out every sin from the inner part of the house into the light of God and walk in the light, the precious blood that justifies will work mightily to cleanse too: the blood brings into living contact with the life and the love of God. Let us come into the light with the sin: the blood will prove its mighty power. Let us cleanse ourselves in yielding ourselves to the light to reveal and condemn, to the blood to cleanse and sanctify.
'Let us cleanse ourselves, _perfecting holiness in the fear of the Lord_.' We read in Hebrews (x. 14), 'Christ hath perfected forever them that are sanctified.' As we have so often seen that what God has made holy man must make holy too, as he accepts and appropriates the holiness God has bestowed, so here with the perfection which the saints have in Christ. We must perfect holiness: holiness must be carried out into the whole of life, and carried on even to its end. As God's holy ones, we must go on to perfection, perfecting holiness. Do not let us be afraid of the word. Our Blessed Lord used it when He gave us the command, 'Be ye perfect, even as your Father in heaven is perfect.' A child striving after the perfection in knowledge of his profession, which he hopes to attain when he has finished school, is told by his teacher that the way to the perfection he hopes for at the end of his course is to seek to be perfect in the lessons of each day. To be perfect in the small portion of the work that each hour brings, is the path to the perfection that will crown the whole. The Master calls us to a perfection like that of the Father: He hath already perfected us in Himself: He holds out the prospect of perfection ever growing. His word calls us here day by day to be perfecting holiness. Let us seek in each duty to be whole-hearted and entire. Let us, as teachable scholars, in every act of worship or obedience, in every temptation and trial, do the very best which God's Spirit can enable us to do. 'Let patience have its perfect work, that ye may be perfect and entire, lacking in nothing.' 'The God of peace make you perfect in every good work to do His will.'
'_Having therefore these promises_, beloved, let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God.' It is faith that gives the courage and the power to cleanse from all defilement, perfecting holiness in the fear of God. It is as the promises of the Divine love and indwelling (2 Cor. vi 16-18) are made ours by the Holy spirit, that we shall share the victory which overcometh the world, even our faith. In the path along which we have already come, from the rest in Paradise down through Holy Scripture, we have seen the wondrous revelation of these promises in ever-growing splendour. That God the Holy One will make us holy; that God the Holy One will dwell with the lowly; that God in His Holy One has come to be our holiness; that God has planted us in Christ that He may be our sanctification; that God, who chose us in sanctification of the Spirit, has given us the Holy Spirit in our hearts, and now watches over us in His love to work out through Him His purposes and to perfect our holiness: such are the promises that have been set before us. 'Having therefore these promises, beloved, let us cleanse ourselves from all filthiness of flesh and spirit, perfecting holiness in the fear of God.'
