Charles H. Spurgeon on Psalms 9:2

"I will confess unto thee, O Lord, with my whole heart," etc. Behold with what a flood of the most sweet affections he says that he "will confess," "show forth," "rejoice," "be glad," and "sing," being filled with ecstasy! He does not simply say, "I will confess," but, "with my heart," and "with my whole heart." Nor does he propose to speak simply of "works," but of the "marvellous works" of God, and of "all" those "works." Thus his spirit (like John in the womb) exults and rejoices in God his Saviour, who has done great things for him, and those marvellous things which follow. In which words are opened the subject of this Psalm: that is, that he therein sings the marvellous works of God. And these works are wonderful, because he converts, by those who are nothing, those who have all things, and, by the ALMUTH who live in hidden faith, and are dead to the world, he humbles those who flourish in glory, and are looked upon in the world. Thus accomplishing such mighty things without force, without arms, without labour, by the cross only and blood. But how will his saying, that he will show forth "all" his marvellous works, agree with that of Job 9:10, "which doeth great things past finding out; yea, and wonders without number"? For, who can show forth all the marvellous works of God? We may say, therefore, that these things are spoken in that excess of feeling in which he said, (Psalm 6:6), "I will water my couch with my tears." That is, he hath such an ardent desire to speak of the wonderful works of God, that, as far as his wishes are concerned, he would set the "all" forth, though he could not do it, for love has neither bounds nor end: and, as Paul saith (1 Corinthians 13:7), "Love beareth all things, believeth all things, hopeth all things;" hence it can do all things, and does do all things, for God looketh at the heart and spirit. Martin Luther.
