Omnipotence means all-powerful. Monotheistic theologians regard God as having supreme power. This means God can do what he wants. ... Being omnipotent, God has power over wind, water, gravity, physics, etc. God's power is infinite, or limitless.

if an omnipotent god exist and make a stone that no one can lift, and if the god can lift the stone does that mean the god is not omnipotent? because he can't make a stone that no one can lift, but if he can't lift the stone doesn't that also mean he's not omnipotent? because there's a thing that he can't do​
