Demons have been known to be more “powerful” than God, at least in the short term.
*sigh*
As with the cross of Christ, so now, God temporarily allows the devil to be active for God's greater purposes.
"[God] raised [Jesus Christ] from the dead, and set him at his own right hand in the heavenly places, Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: And has put all things under his feet..." Eph 1:20-22.
Also remember, God has given us all power over the devil. Jesus said,
"Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you." Luke 10:19
“Demons have been known to be more powerful than God, at least in the short term.”
