Wherefore doth the wicked contemn God? - That is, despise him; or treat him with contempt and disregard. On what ground is this done? How is it to be accounted for? What is the proper explanation of so strange a fact? It is to be observed here:
(a) that the psalmist assumes this to be a fact, that the wicked do thus contemn or despise God. Of this he had no doubt; of this there can be no doubt now. They act as if this were so; they often speak of Him as if this were so. They pay no respect to his commands, to his presence, or to his character; they violate all His laws as if they were not worth regarding; they spurn all His counsels and entreaties; they go forward to meet Him as if His wrath were not to be apprehended or dreaded.
(b) So strange a fact, the psalmist says, ought to be accounted for. There must be some reason why it occurs; and what that reason is, is worth an earnest inquiry. It could not be possible to believe that man - the creature of God, and a creature so weak and feeble - could do it, unless the fact were so plain that it could not be denied. It is, then, worth inquiry to learn how so strange a fact can be accounted for; and the solution - the thing which will explain this, and which must be assumed to be true in order to explain it - is stated in the concluding part of the verse.
He hath said in his heart - This expression is here repeated for the third time in the psalm. See Psalms 10:6, Psalms 10:11. The idea is, that all this is the work “of the heart,” and indicates the state of the heart. It cannot be regarded as the dictate of the reason or the judgment; but it is to be traced to the wishes, the feelings, the desires, and is to be regarded as indicating the real condition of the human heart. A man habitually desires this; he practically persuades himself that this is so; he acts as if it were so.
Thou wilt not require it - Thou wilt not require an account of it; thou wilt not inquire into it. The Hebrew is simply: “Thou wilt not seek;” and the idea is, that God would not make an investigation of the matter. This fact, the psalmist says, would account for the conduct of the wicked. This is the actual feeling of wicked men, that they are not to give account of their conduct, or that God will not be strict to mark their deeds. People act as if they were not responsible to their Maker, and as if it were a settled point that he would never call them to account.
