The threefold repetition of the HOLY has at all times by the Church of Christ been connected with the Holy Trinity. The song of the living creatures around the throne (Rev. iv.) is evidence of the truth of this thought. We there find it followed by the adoration of Him who was, and is, and is to come, the Almighty: the Eternal Source, the present manifestation in the Son, the future perfecting of the revelation of God in the Spirit's work in His Church. The truth of the Holy Trinity is often regarded as an abstract doctrine, with little direct bearing on practical life. So far is this from being the case, that a living faith must root in it: some spiritual insight into the relation and the operation of each of the Three, and the reality of their living Oneness, is an essential element of true growth in knowledge and spiritual understanding.[6] Let us here regard the Trinity specially in its relation to God's Holiness and as the source of ours. What does it mean that we adore the Thrice Holy One? God is not only holy, but makes holy: in the revelation of the Three Persons we have the revelation of the way in which God makes holy. The Trinity teaches us that God has revealed Himself in two ways. The Son is _the Form of God_, His manifestation as He shows Himself to man, the Image in which His unseen glory is embodied, and to which man is to be conformed. The Spirit is _the Power of God_, working in man, and leading him up to that Image. In Jesus, He who had been in the form of God took the form of man; and the Divine Holiness was literally manifested in the form of a human life and the members of a human body. A new holy human nature was formed in Christ, to be communicated to us. In His death His own personal holiness was perfected as human obedience, and so the power of sin conquered and broken. Therefore in the resurrection, through the Spirit of Holiness, He was declared to be the Son of God with power to impart His life to us. There the Spirit of Holiness was set free from the veil of the flesh, the trammels that hindered it, and obtained power to enter and dwell in man. The Holy Spirit was poured out as the fruit of Resurrection and Ascension. And the Spirit is now the Power of God in us, working upwards towards Christ, to reproduce His life and Holiness in us, to fit us for fully receiving and showing forth Him in our lives. Christ from above comes to us as the embodiment of the Unseen Holiness of God: the Spirit from within lifts us up to meet Him, and fits us to receive and make our own all that is in Him.
