John Calvin Commentary Psalms 14:6

"Ye put to shame the counsel of the poor, Because Jehovah is his refuge." — Psalms 14:6 (ASV)

You deride the counsel of the poor. He inveighs against those giants who mock the faithful for their simplicity, in calmly expecting, in their distresses, that God will show himself to be their deliverer. And, certainly, nothing seems more irrational to the flesh than to turn to God when he still does not relieve us from our calamities; and the reason is, because the flesh judges God only according to what it presently perceives of his grace.

Whenever, therefore, unbelievers see the children of God overwhelmed with calamities, they reproach them for their groundless confidence, as it appears to them to be, and with sarcastic jeers laugh at the assured hope with which they rely upon God, from whom, nevertheless, they receive no perceptible aid. David, therefore, defies and derides this insolence of the wicked, and threatens that their mockery of the poor and the wretched, and their charging them with folly in depending upon the protection of God, and not sinking under their calamities, will be the cause of their destruction.

At the same time, he teaches them that there is no decision we can make which is wiser than the decision to depend upon God, and that to rest in his salvation, and on the assistance which he has promised us, even though we may be surrounded with calamities, is the highest wisdom.
