John Chrysostom
You assert that Christ is independent of the Father and operates solely on His own will. Therefore, acknowledge that He has no dependence on the Father and functions by His own authority; I will then take the opportunity to explain the significance of the prayer He expressed, which exemplifies His humility and His role as a builder of the Church—indeed, Christ is akin to Joshua. He demonstrates that He can impart wisdom without the act of prayer. Consider a teacher who, while reviewing letters, does not elicit derogatory remarks about his understanding, for when he inquires about a specific letter, it is evident that he seeks to enlighten his students rather than exhibiting ignorance.

In the same way, Christ did not require prayer for Himself, but desired to encourage you to maintain continual vigilance in prayer, engaging in it faithfully, attentively, and without interruption. By diligence, I refer not only to being alert during night-time but also to remaining vigilant during daylight hours in prayer; such dedication reflects true diligence. While one can sleep during late hours, it is also possible to be awake throughout the day without offering prayers; true wakefulness occurs when the spirit is focused on God and recognizes with Whom it converses and to Whom it speaks. Reflect on the presence of the angels, who stand before Him in reverence, while humanity comes before Him, often distracted and unfocused.
