In the context of the doctrine of exaltation, which says that God was a man who was exalted to Godhead, and Jesus after him, interpret Phillipians 2:6, which says that Jesus was "in the form of God" and "thought it not robbery to be equal with God"?
Hmm, the LDS scriptures (the KJV) does not say that. It reads, speaking of Jesus:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
In this case, the Bible translation matters. These verses are about Jesus' condescension.
Mormons definitely believe that becoming like God is something to aspire to.
Paul taught that when the Savior was born into mortality, He “made himself of no reputation, and took upon him the form of a servant” (Philippians 2:7). Jesus Christ gave up His premortal status “in the form of God” and was born into mortality “in the likeness of men” (Philippians 2:6–7). In the Book of Mormon, the idea of Christ descending below all things is called “the condescension of God” (1 Nephi 11:16; see also verses 17–33; Psalm 22:14; Isaiah 53:12).
Joseph, Mary, Jesus For unto Us a Child Is Born, by Lynne Millman Weidinger
According to Elder Tad R. Callister of the Seventy, “God the Son traded his heavenly home with all its celestial adornments for a mortal abode with all its primitive trappings. He, ‘the King of heaven’ (Alma 5:50), ‘the Lord Omnipotent who reigneth’ (Mosiah 5:3), left a throne to inherit a manger. He exchanged the dominion of a god for the dependence of a babe. He gave up wealth, power, dominion, and the fullness of his glory—for what?—for taunting, mocking, humiliation, and subjection. It was a trade of unparalleled dimension, a condescension of incredible proportions, a descent of incalculable depth” (The Infinite Atonement , 64).
