Who are you, O man, to talk back to God?

(Thomas Watson, "Body of Divinity")

"I will have mercy on whom I have mercy, and I
 will have compassion on whom I have compassion.
 It does not, therefore, depend on man's desire or
 effort, but on God's mercy." Romans 9:15-16

God has a sovereign right and authority over man.
He can do with His creatures as He pleases. Who shall
dispute with God? Who shall ask Him a reason of His
doings? "Who are you, O man, to talk back to
God? Shall what is formed say to him who formed
it—Why did you make me like this?" Romans 9:20

"Our God is in heaven and does whatever He pleases."
 Psalm 115:3

"The Lord does whatever He pleases in heaven and
 on earth, in the seas and all the depths." Psalm 135:6

God sits as judge in the highest court, and is not bound
to give a reason for His proceedings. "He puts down one,
and raises up another." He has salvation and damnation
in His power. He has the key of justice in His hand, to
lock up whomever he will, in the fiery prison of hell! And
He has the key of mercy in His hand, to open heaven's
gate to whomever He pleases! The name engraved upon
His vesture is, "King of kings, and Lord of lords!" He sits
Lord paramount, and who can call Him to account? The
world is God's house, and shall not He do what He
desires in His own house?

"My purpose will stand, and I will do all that I please!"
     Isaiah 46:10

"Hallelujah! For the Lord our God, the Almighty, reigns!"
     Revelation 19:6
