John Calvin Commentary Psalms 86:10

"For thou art great, and doest wondrous things: Thou art God alone." — Psalms 86:10 (ASV)

For thou art great, and thou alone, O God! doest wondrous things. In this verse is again repeated the cause that will bring all nations to worship before the Lord: namely, the discovery of his glory by the greatness of his works. The contemplation of God’s glory in his works is the true way of acquiring genuine godliness.

The pride of the flesh would always lead it to wing its way into heaven; but, as our understandings fail us in such an extended investigation, our most profitable course is, within the limits of our feeble capacity, to seek God in his works, which bear witness to him.

Let us therefore learn to awaken our understandings to contemplate the divine works, and let us leave the presumptuous to wander in their own intricate mazes, which, in the end, will invariably land them in an abyss from which they will be unable to extricate themselves.

To incline our hearts to exercise this modesty, David magnificently extols the works of God, calling them wondrous things, although to the blind, and those who have no taste for them, they are destitute of attraction.

In the meantime, we should carefully attend to this truth: that the glory of the Godhead belongs exclusively to the one true God, for in no other being is it possible to find the wisdom, or the power, or the righteousness, or any of the numerous marks of divinity which shine forth in his wonderful works.

From this it follows that the Papists are chargeable with rendering, as much as is in their power, his title to true Godhead void, when stripping him of his attributes, they leave him with almost nothing but the bare name.
