Charles H. Spurgeon on Psalms 130:5

I wait...I hope. Waiting and hoping ever attend the same thing. No man will wait at all for that which he hath no hope of, and he who hath hope will wait always. He gives not over waiting, till he gives over hoping. The object of hope is some future good, but the act of hoping is at present good, and that is present pay to bear our charges in waiting. The word implies both a patient waiting and a hopeful trusting. So Christ expounds it (Mt 12:21), rendering that of the prophet (Isa 42:1-4), "The isles shall wait for his law", thus, "In his name shall the Gentiles trust." —Joseph Caryl.

Verses 5-6. In these two verses he doth four times make mention of his hope, and attendance upon God and his word, to let us see how sure a hold we should take on God, and with how many temptations our faith is assaulted, when we can see no reason thereof. Nothing will bear us up but hope. Spero meliora. What encourages husbandmen and mariners against the surges and waves of the sea, and evil weather, but hope of better times? What comforteth a sick man in time of sickness, but hope of health? or a poor man in his distress, but hope of riches? or a prisoner, but hope of liberty? or a banished man, but hope to come home? All these hopes may fail, as oftentimes wanting a warrant. Albeit a physician may encourage a sick man by his fair words, yet he cannot give him an assurance of his recovery, for his health depends on God: friends and courtiers may promise poor men relief, but all men are liars; only God is faithful who hath promised. Therefore let us fix our faith on God, and our hope in God; for he will stand by his promise. No man hath hoped in him in vain, neither was ever any disappointed of his hope. —Archibald Symson.
