This distinctness of things argues not a spontaneous generation but a prevenient Cause; and from that Cause we can apprehend - Athanasius of Alexandria

The answer is this. The Lord did not come to make a display. He came to heal and to teach suffering men. For one who wanted to make a display the thing would have been just to appear and dazzle the beholders. But for Him Who came to heal and to teach the way was not merely to dwell here, but to put Himself at the disposal of those who needed Him, and to be manifested according as they could bear it, not vitiating the value of the Divine appearing by exceeding their capacity to receive it.

he neither bathed his body with water to free himself from filth, nor did he ever wash his feet, nor even endure so much as to put them into water, unless compelled by necessity.

Our Lord took on a body like ours and lived as a man in order that those who had refused to recognize Him in His superintendence and capacity of the whole universe might come to recognize from the works He did here below in the body that what dwelled in this body was the Word of God.
