John 1:14:

And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.

David J. MacLeod writes [BibSac 161 (2004), 74–75]:

The words ὁ λόγος σὰρξ ἐγένετο (“the Word became flesh”) are unambiguous, almost shocking. Σάρξ (“flesh”) can speak of the soft parts of the body (skin, muscle, fat) as opposed to blood and bones.

Literally interpreted, flesh/σάρξ is the material that covers the human skeleton [BDAG]. Hence, the Word became skin, muscle, and fat.

We are quite familiar with this life of flesh. We want our skin to be clean, our muscles to be toned, and our fat to be minimized. When we think of humanness, we think primarily of these three things. It was this life of “fleshiness”—of skin, muscle, and fat—that the Savior assumed.

Taking for granted that we affirm the divinity of the Word (Jesus is God), the humanness of the incarnation is simply stunning.
