John Calvin Commentary Psalms 146:6

"Who made heaven and earth, The sea, and all that in them is; Who keepeth truth for ever;" — Psalms 146:6 (ASV)

Who made heaven, etc. By all these epithets he confirms the truth previously stated. For though at first sight it may seem inappropriate to speak of the Creation, the power of God relates most directly to his helping us whenever danger is near. We know how easily Satan tempts us to distrust, and we are thrown into a state of trembling agitation by the slightest causes.

Now, if we reflect that God is the Maker of heaven and earth, we will reasonably give him the honor of having the government of the world which he created in his hands and power. There is in this first ascription, then, a commendation of his power, which should swallow up all our fears.

As it is not enough that God is merely able to help us, but as a promise is further necessary—a promise that he is willing and will do it—David next declares that he is faithful and true, so that, on discovering his willingness, no room may be left for hesitation.
