Omnipotence is a noun for power that has no end: the power to do everything. People use it first about God. In many religions, God has omnipotence — no job is too big, and nobody can say no. That is the old, serious use, and it still lives in church, in religion class, and in books that talk about God. Though actually, the tidy line “able to do everything” hides a fight that has gone on for a very long time. If God can do everything, can God make a stone so heavy that God cannot lift it? People who love this word still argue about that. Outside church, writers stretch it. A newspaper may talk about the omnipotence of a leader, a court, or money. That is loose. It means the power feels huge, not that it is magic. No human has omnipotence. Younger speakers almost never say the word in the street; they say can do anything, or all-powerful. You will meet omnipotence when the writing wants to sound heavy. The adjective is omnipotent.
