Charles H. Spurgeon on Psalms 9:10

"They that know thy name will put their trust in thee: for, thou, Lord, hast not forsaken them that seek thee." The mother of unbelief is ignorance of God, his faithfulness, mercy, and power. They that know thee, will trust in thee. This confirmed Paul, Abraham, Sarah, in the faith. "I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day." 2 Timothy 1:12. "He is faithful that promised," and "able also to perform." Hebrews 10:23, and 11:11; Romans 4:21. The free promises of the Lord are all certain, his commandments right and good, the recompense of reward inestimably to be valued above thousands of gold and silver; trust therefore in the Lord, O my soul, and follow hard after him. Thou hast his free promise, who never failed, who hath promised more than possibly thou couldst ask or think, who hath done more for thee than ever he promised, who is good and bountiful to the wicked and ungodly; thou doest his work, who is able and assuredly will bear thee out. There is a crown of glory proposed to thee above all conceit of merit; stick fast unto his word, and suffer nothing to divide thee from it. Rest upon his promises though he seem to kill thee; cleave unto his statutes though the flesh lust, the world allure, the devil tempt, by flatteries or threatenings to the contrary. John Ball, 1632.
