There lies the problem. Jesus subjecting Himself, somehow makes Him ontologically inferior?
In Philippians 2 for example, prior to Paul speaking of Jesus “being born in the likeness of men” (Philippians 2.7, c.f. John 1.14), there was a voluntary act of self-emptying on behalf of Christ. If Christ was active in His own “kenosis” (which occurred prior to “being born in the likeness of men”) then this is a strong implication of preexistence. Paul elsewhere write, “For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you by his poverty might become rich” (2 Corinthians 8.9) which also assumes preexistence. A preexistence where Jesus is said to exist in the “form of God” (Philippians 2.6, c.f. John 1.1). That Jesus, who has “equality with God” (Philippians 2.6) would set aside His own divine prerogatives and enter into creation is the ultimate display of humility that Paul formerly mentions in Philippians 2.3-4. Jesus subjects Himself here, yet the text can still speak of Him as being equal to God.
I think one needs to understand that the equality that is spoken of throughout the NT is one of nature.

Another view is that Jesus was saying that He didn’t consider existing in the form of God as something to be grasped. This view has always been highly contested though. This is based upon how the Greek reads. Philippians 2:6 Interlinear: who, being in the form of God, thought it not robbery to be equal to God, Either way you look at it though, it mentions nothing of power. Simply form.
Jesus did empty Himself by taking on the “form” of a man, no longer in His divine nature. This does not prove equality at all though, as even an angel taking on the form of a man would have to empty oneself as well. We are said to be made a little lesser than the angels after all.
Again it is equal in “morphe” (form), not Power. Also you have to recognize that God is being contrasted here with Christ. This is clearly showing God to be a separate entity than Christ. “did not consider equality with God as something to be used for His own advantage” God is spoken of as a separate entity to Christ. I see this quite often in scripture though.
