Is the Bible contradictory about God's visibility?

This issue involves a host of verses in which God is said to be "seen" in some way, and these are variously set against the following:

John 1:18 No man hath seen God at any time.(cf. John 6:46)
Exodus 33:20 And he said, Thou canst not see my face; for there shall no man see me and live.
1 Tim. 6:16 Whom no man hath seen nor can see.

A general answer often given is that these verses indicate that God cannot be seen by men when in his full glory. God can be seen when in lesser form - as in the incarnation of Jesus Christ, or a theophany. These lesser forms are indicated, although their nature probably not fully understood by all of the writers, in Exod. 24:9,10, Amos 9:1, Gen. 26:2 and 32:30, John 14:9, and Ex. 33:11.

This response is basically correct, but requires some further elucidation. We shall analyze the relevant verses in a chronological order so that we can see, not a contradiction, but a paradox that is unraveled before our eyes.

Our conclusion: The objection that asks whether or not God can be seen rests upon a lack of linguistic and theological knowledge.
