The created intellect will see God in His essence, and not in any mere likeness. In the latter kind of vision, the object understood may be at a distance from the present intellect; for example, a stone is present to the eye by its likeness, but is absent in substance. But, as was shown above, God’s very essence is in some mysterious way united to the created intellect, so that God may be seen just as He is. Thus, when we arrive at our last end, what was formerly believed about God will be seen, and what was hoped for as absent will be closely embraced as present. This is called comprehension, according to the expression used by the Apostle in Philippians 3:12: “I press on, that I may grasp it.” This is not to be understood in the sense that comprehension implies all-inclusive knowledge, but in the sense that it denotes the presence and a certain clasping of what is said to be comprehended.

All scripture is given by inspiration of God and is profitable for doctrine, reproof, correction, and instruction in righteousness (2 Timothy 3:16).
