Satan and God do not engage in hand-to-hand combat, with Satan sometimes getting the edge. That's not the Bible, that's Star Wars.
Satan is called the "god of this world" (2 Corinthians 4:4, ESV), "the prince of the power of the air" (Ephesians 2:2, ESV), and one of the "cosmic powers over this present darkness: (Ephesians 6:12, ESV). But Scripture always describes Satan's power in the context of God's absolute sovereignty. Satan remains under God's authority at all times. The devil is nowhere close to being omnipotent, omniscient, omnipresent, or in an other way on God's level.
