“As for me, I will behold Thy face in righteousness; I shall be satisfied, when I awake, with Thy likeness.”- Psalm 17:15

It would be difficult to say to which the gospel owes most, to its friends or to its enemies…Jesus Christ would never have preached many of His discourses had not His foes compelled Him to answer them; had they not brought objections, we should not have heard the sweet sentences in which He replied. So with the book of Psalms: had not David been sorely tried by enemies, had not the foemen shot their arrows at him, had they not attempted to malign and blast his character, had they not deeply distressed him, and made him cry out in misery, we should have missed many of those precious experimental utterances we here find, much of that holy song which he penned after his deliverance, and very much of that glorious statement of his trust in the infallible God. We should have lost all this, had it not been wrung from him by the iron hand of anguish…Then was it that he gave honour to God, then he shouted aloud to that mighty Jehovah, who for him had gotten the victory. This sentence follows a description of the great troubles which the wicked bring upon the righteous, wherein he consoles himself with the hope of future bliss.; As for me,” says the patriarch, casting his eyes aloft; As for me,” said the hunted chieftain of the caves of Engedi-“As for me,” says the once shepherd boy, who was soon to wear a royal diadem-“As for me, I will behold Thy face in righteousness, I shall be satisfied, when I awake with Thy likeness.” ~ C.H. Spurgeon
