What does it mean that God is omnipotent? The word can be rendered all-powerful. God himself provided the biblical definition of his omnipotence when he appeared to Abraham and asked this rhetorical question in Genesis 18: “Is anything too hard for the LORD?” In other words, there is nothing that God cannot do that he wants to do. God has internal limits on his own actions that are based on his character. For example, God can’t lie. In fact, God can’t commit any sin. But we need to understand that anything God can’t do is based on his own character. There is nothing outside of God that can thwart his will, or prevent him from doing anything he wants. He has the power to do whatever he pleases.
