There is no union so intimate, so real, so perfect, as that of an indwelling life. Think of the life that circulates through a large and fruitful tree. How it penetrates and fills every portion; how inseparably it unites the whole as long as it really is to exist!--in wood and leaf, in flower and fruit, everywhere the indwelling life flows and fills. This life is the life of nature, the life of the Spirit of God which dwells in nature. It is the same life that animates our bodies, the spirit of nature pervading every portion of them with the power of sensibility and action. Not less intimate, yea rather, far more wonderful and real, is the indwelling of the Spirit of the New Life, through whom God dwells in the heart of the believer. And it is as this indwelling becomes a matter of conscious longing and faith, that the soul obeys the command, 'Let them make me a holy place, that I may dwell among them,' and experiences the truth of the promise, 'The tent shall be sanctified by my glory, and I will dwell among the children of Israel.' It was as the Indwelling One that God revealed Himself in the Son, whom He sanctified and sent into the world. More than once our Lord insisted upon it, 'Believe me, that I am in the Father and _the Father in me_; the Father _abiding in me_ doeth the works.' It is specially as the temple of God that believers are more than once called holy in the New Testament: 'The temple of God is _holy_, which temple ye are.' 'Your body is a temple of the _Holy_ Spirit.' 'All the building groweth unto an holy temple in the Lord.' It is--we shall later on learn to understand this better--just because it is through the Spirit that the heart is prepared for the indwelling, and the indwelling effected and maintained, that the Spirit so peculiarly takes the attribute of Holy. The Indwelling Spirit is the Holy Spirit. The measure of His indwelling, or rather of His revealing the Indwelling Christ, is the measure of holiness. We have seen what the various degrees of nearness to God's Presence in Israel were. They are still to be found. You have Christians who dwell in the camp, but know little of drawing nigh to the Holy One. Then you have outer court Christians: they long for pardon and peace, they come ever again to the altar of atonement; but they know little of true nearness or holiness; of their privilege as priests to enter the holy place. Others there are who have learnt that this is their calling, and long to draw near, and yet hardly understand the boldness they have to enter into the Holiest of all, and to dwell there. Blessed they to whom this, the secret of the Lord, has been revealed. _They know_ what the rent veil means, and the access into the immediate Presence. The veil hath been taken away from their hearts: they have found the secret of true holiness in the Indwelling of the Holy One, the God who is holy and makes holy.
