Why would Jesus have to ever pray or speak in the Spirit, He is God. He created everything including Tongues of humans, animals sounds, Spiritual Tongues.
Your post makes no sense, unless I contort my mind to that of an unbeliever. And then it makes perfect sense, because of the lack of knowledge!!
Jesus as our Faithful Creator speaks the word of God in His Spirit. (God is Sprit) as a work of His faith or called a labor of His love. In the garden the beginning of His three day labor of love . As he sweat to show he was working pouring out His Spirit as if it was blood. He cried out or prayed to the father working together as one work of faith. The Son in submission to the father and the father submitting to the Son in perfect harmony sent a message to the Son strengthening Jesus so that together they can bring the peace of God that surpasses all human understanding.
Sweat is used to represent the Holy Spirit doing His work .
