Such, then, was the double character of the revelation made to Moses at Mount Horeb. What he saw and what he heard combined the two elements of holiness and grace,--elements which, as we know, enter into and distinctly characterize all the ways and all the relationships of the blessed God, and which should also mark the ways of all those who in any wise act for, or have fellowship with, Him. Every true servant is sent forth from the immediate presence of God, with all its holiness and all its grace; and he is called to be holy and gracious--he is called to be the reflection of the grace and holiness of the divine character; and, in order that he may be so, he should not only start from the immediate presence of God at the first, but abide there, in spirit, habitually. This is the true secret of effectual service. "Childlike, attend what Thou wilt say, Go forth and do it, while 'tis day, Yet never leave my sweet retreat." The spiritual man alone can understand the meaning of the two things, "go forth and do," and, "yet never leave." In order to act _for_ God outside, I should be _with_ Him inside. I must be in the secret sanctuary of His presence, else I shall utterly fail. Very many break down on this point. There is the greatest possible danger of getting out of the solemnity and calmness of the divine presence, amid the bustle of intercourse with men, and the excitement of active service. This is to be carefully guarded against. If we lose that hallowed tone of spirit which is expressed in "the unshod foot," our service will very speedily become vapid and unprofitable. If I allow my work to get between my heart and the Master, it will be little worth. We can only effectually serve Christ as we are enjoying Him. It is while the heart dwells upon His powerful attractions that the hands perform the most acceptable service to His name; nor is there any one who can minister Christ with unction, freshness, and power to others, if he be not feeding upon Christ, in the secret of his own soul. True, he may preach a sermon, deliver a lecture, utter prayers, write a book, and go through the entire routine of outward service, and yet not minister Christ. The man who will present Christ to others must be occupied with Christ for himself.
