[6] The Divine necessity and meaning of the doctrine of the Trinity is seen from the counterpart we have of it in nature. In every living object that exists we distinguish first _the life_, then _the form_ or _shape_ in which that life manifests itself, then _the power_ or _effect_ as seen in the result which the life acting in its form or manifestation produces. And so we have God as the Unseen One, the Fountain of life; the Son as the Form or Image of God, the manifestation of the Unseen Life; and the Holy Spirit as the Power of that life proceeding from the Father and the Son, and working out the purpose of God's will in the Church. Applying this thought to God as the Holy One, we shall understand better the place of the Son and the Spirit as they bring to us the Holiness of God. Thirteenth Day. HOLY IN CHRIST. Holiness and Humility. 'Thus saith the High and Lofty One that inhabiteth eternity, whose name is _Holy_: I dwell in the High and _Holy_ place, with him that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.'--Isa. lvii. 15. Very wonderful is the revelation we have in Isaiah of God, the Holy One, as the Redeemer and the Saviour of His people. In the midst of the people whom He created and formed for Himself, He will as the Holy One dwell, showing forth His power and His glory, filling them with joy and gladness. All these promises have, however, reference to the people as a whole. Our text to-day reveals a new and specially beautiful feature of the Divine Holiness in its relation to the individual. The High and Lofty One, whose name is Holy, and whose only fit dwelling-place is eternity, He looks to the man who is of a humble and contrite heart; with him will He dwell. God's Holiness is His condescending Love. As it is a consuming fire against all who exalt themselves before Him, it is to the spirit of the humble like the shining of the sun, heart-reviving and life-giving.
