“And those who know your name will put their trust in you.” — Ps 9:10
There is a knowing of God’s name. By the “name of God” are to be understood the revealed perfections of the Almighty—all that he has revealed concerning himself in the Scriptures of truth. Every attribute, every perfection, everything that God has said of himself, is summed up in the “name of God.”
But especially does the “name of God” signify the Son of his love, who is “the brightness of his glory, and the express image of his Person;” as he said to Moses, “Behold, I send an Angel before you, to keep you in the way, and to bring you into the place which I have prepared. Beware of him and obey his voice, provoke him not; for he will not pardon your transgressions—for my name is in him;” that is, all my revealed perfections, all my glorious character, all my divine attributes are in him; for “in him dwells all the fullness of the Godhead bodily.”
Now, there is a knowing this name of God; that is, there is such a thing as an experimental acquaintance in the soul with the perfections of God as revealed in the Scriptures. His name is therefore known when the perfections of God are revealed in the heart and conscience by the power of the Spirit. And this is by virtue of living faith in the soul. By faith we see God. By faith we know God. When we receive into our hearts the truth as it is in Jesus, and when we believe by living faith what God has said of himself in the word, then we know the name of God; and every manifestation of God’s mercy, every token of God’s favor, and every shining in of God’s perfections, is a discovery in our hearts, a raising up in our souls of the knowledge of God’s name.
