Throughout history, people who hold positions of great power (and those under them) have been caught up in the comparison game. How does your nation, your ruler, and your god[s] stack up against those around?
We see this with figures in the bible. Nebuchadnezzar (Babylon) is called the king of kings (Ezek. 26:7; Dan. 2:37). Cyrus the Great (Persia) and other leaders that follow him like Xerxes and Artexerxes bear that moniker. We see it with Alexander the Great. And when the Romans take power and move from a republic to an empire with an emperor, then the Caesars began to be described in those terms--king of kings, lord of lords. What's more, the Caesars began to be described in other ways that tread on the territory of Jesus. The birth of a new Caesar was described as "gospel/good news" and the Caesars were described as a "son of god, savior, bringer of peace."
So throughout scripture, God the Father and God the Son bear similar titles-God of gods, King of kings, Lord of lords (Deut. 10:17; 1 Tim. 6:15; Rev. 17:14). Jesus is presented as the bringer of gospel, of peace. He is the rightful Son of God and Savior. The writers of scripture like the prophets and gospel writers did not shy away from the comparisons. They welcomed them, and not just because they were convinced about the superiority of God the Father and Son, although they were. It was because they knew what set them apart. What ruler (or god) didn't claim great might, power, or authority? What distinguished Jesus is that his strength was displayed most fully through suffering and sacrifice. His might was used for mercy. His powers were used to feed the hungry, free the imprisoned, invite the outcasts, empower women, and include the foreigner. Jesus showed he is Lord of all by becoming the lover and liberator of all. The claims are easy. But when viewed side by side, there is no comparison.
