Vs. 18 — Open my eyes, that I may see Wondrous things from Your law.

William Cowper:

“Open thou mine eyes.” If it be asked, seeing David was a regenerate man, and so illumined already, how is it that he prays for the opening of his eyes? The answer is easy: that our regeneration is wrought by degrees. The beginnings of light in his mind made him long for more; for no man can account of sense, but he who hath it. The light which he had caused him to see his own darkness; and therefore, feeling his wants, he sought to have them supplied by the Lord.

Paulus Palanterius:

Who is able to know the secret and hidden things of the Scriptures unless Christ opens his eyes? Certainly, no one; for “No man knoweth the Son but the Father; neither knoweth any man the Father save the Son, and he to whom the Son will reveal him.” Wherefore, as suppliants, we draw near to him, saying, “Open thou mine eyes,” etc. The words of God cannot be kept except they be known; neither can they be known unless the eyes shall be opened,—hence it is written, “That I may live and keep thy word;” and then, “Open thou mine eyes.”

Prayer:

Open my eyes, Lord, but not mine alone. Open the eyes of the Church that we may see wondrous things from Your law. We want to see more treasures within Your word. Most of all, we want to see You in Your word. Let our eyes see You that we may know You and walk with You.
