Charles H. Spurgeon on Psalms 30:3

O Lord, thou hast brought up my soul from the grave. Mark, it is not "I hope so; "but it is, "Thou hast; thou hast; thou hast" —three times over. David is quite sure, beyond a doubt, that God has done great things for him, whereof he is exceeding glad. He had descended to the brink of the sepulchre, and yet was restored to tell of the forbearance of God; nor was this all, he owned that nothing but grace had kept him from the lowest hell, and this made him doubly thankful. To be spared from the grave is much; to be delivered from the pit is more; hence there is growing cause for praise, since both deliverances are alone traceable to the glorious right hand of the Lord, who is the only preserver of life, and the only Redeemer of our souls from hell.
