Seraphims

"In the year that King Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
"Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly."

We notice again the pairing of wings. In this picture the wings seem to serve another purpose. Two wings cover the Lord’s face. His face is hidden from men. Just as when Jehovah would lift up his countenance upon Israel, it symbolized his favor and blessing.
When he turned his face away from them it was usually their period of punishment. When the LORD JESUS covers his face from men, they cannot see his countenance and his favor is turned away from them.

With "twain he covered his feet." The feet of Jesus are his body members which make contact with the world. Isaiah says regarding these feet:

"How beautiful upon the mountains are the feet of him that bringeth good tidings, who publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth." Isaiah 52:7

It is the feet of the Christ at this end of the age who are engaged in such glorious work. These poor feet are beautiful to God and to the risen Christ, but the world holds them in contempt, even as they did the Master. The feet members should be beautiful in our eyes, as we see them with painstaking efforts trying to walk in the footsteps of the Master and bearing witness to the glorious plan of the ages.

"With twain he did fly." Two wings carry forth the mission of Christ. We believe these two wings are closely identified with the Words of the Old and New Testaments. Our Lord moves irresistibly forward in carrying out the Holy Word. Not a jot or tittle fails of fulfillment. Heaven and earth could pass more easily than for any part of God’s Word to fail. God has placed the carrying forth of His plan in the hands of His beloved Son.
