Charles H. Spurgeon on Psalms 119:100

I understand...because l keep. Would we know the Lord? Let us keep his commandments. "By thy precepts, "saith David, that is, by the observance of thy precepts, "I get understanding." "If any man do my will" (saith our blessed Saviour, John 7:17), "he shall know my doctrine." boulei yeololov lenesyai? tav entolav fulasse, saith Nazienzen: Wouldst thou be a divine? do the commandments; for action is (as it were) the basis of contemplation. It is St. Gregory's observation concerning the two disciples who, whilst Christ talked with them, knew him not; but in performing an act of hospitality towards him, to wit, breaking bread with him, they knew him, that they were enlightened, not by hearing him, but by doing divine precepts, Quisquis ergo vult audita intelligere; festinet ea quae jam audire potuit, opere implere, Whosoever therefore will understand, let him first make haste to do what he heareth. Nathanael Hardy, 1618-1670.
