Charles H. Spurgeon on Psalms 17:1

"Hear the right, O Lord." He that has the worst cause makes the most noise; hence the oppressed soul is apprehensive that its voice may be drowned, and therefore pleads in this one verse for a hearing no less than three times. The troubled heart craves for the ear of the great Judge, persuaded that with him to hear is to redress. If our God could not or would not hear us, our state would be deplorable indeed; and yet some professors set such small store by the mercy-seat, that God does not hear them for the simple reason that they neglect to plead. As well have no house if we persist like gipsies in living in the lanes and commons; as well have no mercy-seat as be always defending our own cause and never going to God. There is more fear that we will not hear the Lord than that the Lord will not hear us. "Hear the right;" it is well if our case is good in itself and can be urged as a right one, for right shall never be wronged by our righteous Judge; but if our suit be marred by our infirmities, it is a great privilege that we may make mention of the righteousness of our Lord Jesus, which is ever prevalent on high. Right has a voice which Jehovah always hears; and if my wrongs clamour against me with great force and fury, I will pray the Lord to hear that still louder and mightier voice of the right, and the rights of his dear Son. "Hear, O God, the Just One;" i.e., "hear the Messiah," is a rendering adopted by Jerome, and admired by Bishop Horsley, whether correct or not as a translation, it is proper enough as a plea. Let the reader plead it at the throne of the righteous God, even when all other arguments are unavailing. "Attend unto my cry." This shows the vehemence and earnestness of the petitioner; he is no mere talker, he weeps and laments. Who can resist a cry? A real hearty, bitter, piteous cry, might almost melt a rock, there can be no fear of its prevalence with our heavenly Father. A cry is our earliest utterance, and in many ways the most natural of human sounds; if our prayer should like the infant's cry be more natural than intelligent, and more earnest than elegant, it will be none the less eloquent with God. There is a mighty power in a child's cry to prevail with a parent's heart. "Give ear unto my prayer." Some repetitions are not vain. The reduplication here used is neither superstition nor tautology, but is like the repeated blow of a hammer hitting the same nail on the head to fix it the more effectually, or the continued knocking of a beggar at the gate who cannot be denied an alms. "That goeth not out of feigned lips." Sincerity is a sine quà non in prayer. Lips of deceit are detestable to man and much more to God. In intercourse so hallowed as that of prayer, hypocrisy even in the remotest degree is as fatal as it is foolish. Hypocritical piety is double iniquity. He who would feign and flatter had better try his craft with a fool like himself, for to deceive the all-seeing One is as impossible as to take the moon in a net, or to lead the sun into a snare. He who would deceive God is himself already most grossly deceived. Our sincerity in prayer has no merit in it, any more than the earnestness of a mendicant in the street; but at the same time the Lord has regard to it, through Jesus, and will not long refuse his ear to an honest and fervent petitioner.
