Who only has immortality, dwelling in the light which no man can approach unto; whom no man has seen, nor can see: to whom be honor and power everlasting. Amen.
All Commentaries on 1 Timothy 6:16 Go To 1 Timothy 6
Augustine of Hippo
AD 430
If you ask whether he can also be seen at any time as he is, I answer that this was promised to his sons, of whom it is said, “We know that when he shall appear, we shall be like him, because we shall see him as he is.” If you ask by what means we shall see him, I answer: as the angels see, for we shall then be equal to them, as the angels see those things which are called visible; but no one has ever seen God nor can see him, because “he inhabits light inaccessible,” and his nature is invisible as it is immortal. .
