Andrew Murray emphasizes the high privilege of being a child of God, which includes unbroken fellowship with the Father and the assurance that all that God has is available to His children. He illustrates this privilege by referencing God's promises to figures like Enoch and Jacob, highlighting that God's presence is a mark of His people. Murray encourages believers to recognize that they are called to live in constant communion with God, filled with the Holy Spirit, and to enjoy the light of His countenance. He reminds us that this relationship is not just for the Old Testament saints but is a reality for all believers today. Ultimately, the sermon calls Christians to embrace their identity as children of God and to live in the fullness of His presence.

We have here two things describing the privilege: —First, “Son, thou art ever with me”—unbroken fellowship with thy Father is thy portion; Second, “All that I have is thine ”—all that God can bestow upon His children is theirs. “Thou are ever with me;” I am always near thee; thou canst dwell every hour of thy life in My presence, and all I have is for thee. I am a father, with a loving father’s heart. I will withhold no good thing from thee. In these promises, we have the rich privilege of God’s heritage. We have, in the first place, unbroken fellowship with Him. A father never sends his child away with the thought that he does not care about his child knowing that he loves him. The father longs to have his child believe that he has the light of his father’s countenance upon him all the day—that, if he sends the child away to school, or anywhere that necessity compels, it is with a sense of sacrifice of parental feelings. If it be so with an earthly father, what think you of God? Does He not want every child of His to know that he is constantly living in the light of His countenance? This is the meaning of that word, “Son, thou art ever with me.” That was the privilege of God’s people in Old Testament times. We are told that “Enoch walked with God.” God’s promise to Jacob was: “Behold, I am with thee, and will keep thee in all places whither thou goest , and will bring thee again into this land; for I will not leave thee until I have done that which I have spoken to thee of.” And God’s promise to Israel through Moses, was: “My presence shall go with thee, and I will give thee rest.” And in Moses’ response to the promise, he says, “For wherein shall it be known that I and Thy people have found grace in Thy sight? Is it not that Thou goest with us; so shall we be separated, I and Thy people, from all the people that are upon the face of the earth.” The presence of God with Israel was the mark of their separation from other people. This is the truth taught in all the Old Testament; and if so, how much more may we look for it in the New Testament? Thus we find our Saviour promising to those who love Him and who keep His word, that the Father also will love them, and Father and Son will come and make Their abode with them. Let that thought into your hearts—that the child of God is called to this blessed privilege, to live every moment of his life in fellowship with God. He is called to enjoy the full light of His countenance. There are many Christians—I suppose the majority of Christians—who seem to regard the whole of the Spirit’s work as confined to conviction and conversion: —not so much that He came to dwell in our hearts, and there reveal God to us. He came not to dwell near us, but in us, that we might be filled with His indwelling. We are commanded to be “filled with the Spirit;” then the Holy Spirit would make God’s presence manifest to us. That is the whole teaching of the epistle to the Hebrews: —the veil is rent in twain; we have access into the holiest of all by the blood of Jesus; we come into the very presence of God, so that we can live all the day with that presence resting upon us. That presence is with us wheresoever we go; and in all kinds of trouble, we have undisturbed repose and peace. “Son, thou art ever with me.”
