Why did Jesus think it not robbery to be equal with God?

He thought it not robbery to be equal with God because He was God. Philippians 2:6 says Christ Jesus, being in the form of God, thought it not robbery to be equal with God, because He was God. Scripture declares this truth, which is beyond human comprehension.

Les teaches that Philippians 2:6-7 is beyond human comprehension, yet it is what the Word declares. Christ Jesus, being in the form of God, thought it not robbery to be equal with God because He was God. Although He possessed all the wealth of the universe, for our sakes He became poor—so poor that foxes have holes and birds have nests, but the Son of Man had no place to lay His head. That was a graphic illustration in the material realm; in the spiritual realm He went far deeper into absolute poverty.

Philippians 2:6

Who, being in the form of God, thought it not robbery to be equal with God:

Why did Jesus not consider equality with God something to be grasped in Philippians 2:6?

Christ did not regard equality with God as something to be seized or robbed because He already possessed it by nature. Being in the form of God, He was God, so equality was not an external prize to grasp but His inherent identity.
