If God's mercies thus baffle enumeration and beggar praise, the question naturally rises, "What shall I render to the Lord for all His benefits?" Therefore the next turn of thought shows the psalmist as reaching the lofty spiritual conception that heartfelt delight in God's will is the true response to God's wonders of love. He soars far above external rites as well as servile obedience to unloved authority, and proclaims the eternal and ultimate truth that what God delights in is man's delight in His will. The great words which rang the knell of Saul's kingship may well have sounded in his successor's spirit. Whether they are the source of the language of our psalm or not, they are remarkably similar. "To obey is better than sacrifice, and to hearken than the fat of rams" (1 Sam. xv. 23), teaches precisely the same lesson as vv. 6-8 of this psalm. The strong negation in ver. 6 does not deny the Divine institution of the sacrificial law, but affirms that something much deeper than external sacrifices is the real object of God's desire. The negation is made emphatic by enumerating the chief kinds of sacrifice. Whether they are bloody or bloodless, whether meant to express consecration or to effect reconciliation, they are none of them the true sacrifices of God. In ver. 6 the psalmist is entirely occupied with God's declarations of His requirements; and he presents these in a remarkable fashion, intercalating the clause, "Ears hast Thou pierced for me," between the two parallel clauses in regard to sacrifice. Why should the connection be thus broken? The fact that God has endowed the psalmist with capacity to apprehend the Divine speech reveals God's desire concerning him. Just because he has ears to hear, it is clear that God wishes him to hear, and therefore that outward acts of worship cannot be the acknowledgment of mercies in which God delights. The central clause of the verse is embedded in the others, because it deals with a Divine act which, pondered, will be seen to establish their teaching. The whole puts in simple, concrete form a wide principle, namely, that the possession of capacity for receiving communications of God's will imposes the duty of loving reception and obedience, and points to inward joyful acceptance of that will as the purest kind of worship.
