This is “the glorious and fearful name” 2Deuteronomy 28:58. of the Lord, which no man can ever comprehend, because it expresses His infinity and eternity. Look at the renderings that are given in the margin of the Revision: “I am because I am,” or “I am who I am,” or “I will be that I will be.” No one of these renderings is complete in itself, but all of them together are necessary to give something of an idea of the title. Together they represent “The Lord which is, and which was, and which is to come, the Almighty.” 3Revelation 1:8. EVCO 179.1
How fitting that when the Lord was about to deliver the people, not simply from temporal bondage, but from spiritual bondage as well, and give to them that inheritance which could be possessed only by the coming of the Lord and the resurrection, He should make Himself known not only as the self-existent Creator, but as The Coming One, the same title by which He reveals Himself in the last book of the Bible, which is wholly devoted to the coming of the Lord and the final deliverance of His people from their great enemy, death. EVCO 179.2
