The answer
No, He was not speaking to Himself, but to His Father. The triunity of God has always been inseparable, not just for a season, and neither beginning at the incarnation did the Lord Jesus Christ become the Son of God, but has always existed, co-essential with the Father and the Holy Spirit. In, John 15:1-17, the Lord Jesus Christ illustrated the intricate relationship between the Holy Trinity and us. In Christ's humanity, He submitted to God the Father in complete obedience: "Let this mind be in you which was also in Christ Jesus, who, being in the form of God, did not consider it robbery to be equal with God, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross" (Philippians 2:5). Thus, in His prayers, He demonstrates His inseparable relationship with the eternal Holy Trinity, as well as the necessary life of prayer and submission to God's will as the Son of God, and as a pattern of life for us to follow as children of God.Answered by His Eminence Metropolitan Youssef (opens in a new tab)
