Charles H. Spurgeon on Psalms 115:3

And our God (is) in heaven; all that he pleased he has done. The "and, "though foreign from our idiom, adds sensibly to the force of the expression. They ask thus, as if our God were absent or had no existence; and yet all the while our God is in heaven, in his exalted and glorious dwelling place. Joseph Addison Alexander.

Verse 3 (first clause). It would be folly to assert the like concerning idols; therefore, if the heathen say, Where is your God? we reply, He is in heaven, &c.: but where are your idols? In the earth, not making the earth, but made from the earth, &c. Martin Geier.
