We have already seen how holiness in its very nature supposes the personal relation to God, His personal presence. 'I have brought you _unto myself_; if ye obey, ye shall be _unto me_ an holy nation.' It is as we understand and hold fast this personal element that obedience will become possible, and will lead to holiness. Mark well God's words: 'If ye will obey my _voice_, and keep my covenant.' The voice is more than a law or a book; it always implies a living person and intercourse with him. It is this that is the secret of gospel obedience: hearing the voice and following the lead of Jesus as a personal friend, a living Saviour. It is being led by the Spirit of God, having Him to reveal the Presence, and the Will, and the Love of the Father, that will work in us that personal relation which the New Testament means when it speaks of doing everything unto the Lord, as pleasing God. Such obedience is the pathway of holiness. Its every act is a link to the living God, a surrender of the being for God's will, for God Himself to take possession. In the process of assimilation, slow but sure, by which the will of God, as the meat of our souls, is taken up into our inmost being, our spiritual nature is strengthened, is spiritualized, growing up into an holy temple in which God can reveal Himself and take up His abode. Let every believer study to realize this. When God sanctified the seventh day as His period of making holy, He taught us that He could not do it at once. The revelation and communication of holiness must be gradual, as man is prepared to receive it. God's sanctifying work with each of us, as with the race, needs time. The time it needs and seeks is the life of daily, hourly obedience. All that is spent in self-will, and not in the living relation to the Lord, is lost. But when the heart seeks day by day to hearken to the voice and to obey it, the Holy One Himself watches over His words to fulfil them: 'Ye shall be unto me an holy nation.' In a way of which the soul beforehand can have but little conception, God will overshadow and make His abode in the obedient heart. The habit of always listening for the voice and obeying it will only be the building of the temple: the Living God Himself, the Holy One, will come to take up His abode. The glory of the Lord will fill the house, and the promise be made true, 'I will sanctify it by my glory.'
