ISB ~ Philippians 2 v6

though he was:Could also be translated, “because he was”.

• There is a close relationship between the divine and human life of Jesus, so that the human actions of Christ in history reveal the mystery of his divine activity in eternity. By pouring himself out to the Father in death, he displays how his love is poured out to the Father in the dynamism of life within God. The loving obedience of Christ is thus an act of divine revelation, showing the world the life-giving love that flows from Person to Person in the hidden embrace of the Trinity. See note Jn 14:31.

the form:The Greek term morphē, used here to assert the divinity of Christ, is used again in the next verse to assert his full humanity (2:7). Some take the “form of God” to be equivalent to the human “image” of God in Gen 1:26, but this is unlikely because the passage concerns the preexistent life of Christ before he entered the world as a man.
