John 9:38

Now is the work of faith with power wrought in his soul: he saith, Lord, I do acknowledge and receive thee as the Son of God; I am fully persuaded that thou art more than what thou art in thy external form and appearance, more than a mere man, and I give up myself to thee, to be ruled and guided by thee. And as a testimony of this, he performed some act of external adoration to him. The word signifies prostration; he kneeled down to him, or he fell upon his face before him: we are not able to determine what particular act or posture of adoration he used; but there is nothing plainer, than that it is to be understood of such a Divine adoration and homage as is due unto God alone, for it was such as testified his faith in him as the Son of God, whom he had professed that he believed him to be, in the words immediately preceding: although therefore the word in the Greek be a word used sometimes to signify that civil respect which men show to their superiors, yet it cannot be so interpreted in this place, considering what went before.
