Israel"s God was not on earth, as the idols were. He is in heaven, and He does whatever He pleases. The psalmist did not mean that Yahweh is capricious but that He is a free agent, independent of the actions of His worshippers. God is sovereign. In contrast, the gods Israel"s neighbors worshipped were human products made, in some cases, out of metal, even though costly metal. They had some of the attributes of human beings but were totally impotent and lifeless. All human beings tend to become like their God or gods. Idol worshippers become as powerless as their gods.
