The UFC contest between the LORD and Dagon is in 1 Samuel 5:2-4.
Round One …and he's up again!:
"Then the Philistines took the ark of God and brought it to the house of Dagon and set it by Dagon. When the Ashdodites arose early the next morning, behold, Dagon had fallen on his face to the ground before the ark of the LORD."
Round Two: …and he is down for the count!:
"So they took Dagon and set him in his place again. But when they arose early the next morning, behold, Dagon had fallen on his face to the ground before the ark of the LORD. And the head of Dagon and both the palms of his hands were cut off on the threshold; only the trunk of Dagon was left to him."
Of Course the Lord wins the contest with any idol! What is surprising is that the Lord allowed the fight to extend to two rounds. God does His works in time to make His works a teaching moment for His people. He created the heavens and the earth over a six day period. He destroyed Egypt and saved His people over the course of ten plagues. He defeated Dagon in two steps. He is doing a work in your life over the course of your entire lifetime. A single day is not a good measure of Christ's victories in your life. Sometimes not even a year reveals how God is succeeding. God's victorious work in the life your life may only be measurable over a decade or a lifetime or eternity.
For I am confident of this very thing,
For me to live is Christ.
