As Kefa says, ‘G-d, having raised up His servant, sent him to you first, to bless you by turning every one of you from your wickedness’ (Ma’asei / Acts 3:26).
Like Son of G-d, it should go without saying that the Servant of G-d is not G-d Himself. G-d is not the the one He formed from the womb to be His servant, to bring Ya’akov (Jacob) back to Him, and that Yisrael (Israel) might be gathered to Him, a servant who has a G-d (cf. Yeshayahu / Isaiah 49:3,5).
HaShem is clearly not speaking of Himself here, but of His Son, the heavenly power (Hb. elohim, Gk. theos) who emptied himself, taking on the form of a servant, being born in the fashion of men, becoming obedient to the point of death, and being therefore exalted by G-d, the Father (cf. Philippians 2:6-11).
