A sincere but sincerely lost and deceived child of Jacob denies Messiah’s deity because Jesus prays to the Father.
Jesus prays to God the Father because the Son and the Spirit commune with the Father and have delineated authority to the Father and His will in all things. Jesus left the Spiritual Realm (John 18:36) and entered the Realm of Time to do the Father’s will, not his own (John 6:38); specifically, Jesus entered Time “to destroy the works of the Devil” (1 John 3:8b).
It is the Father that Satan rebelled against, specifically (Ezekiel 28:11-19); it is the Father who is responsible via federal headship for the Kingdom and order-peace-righteousness in that Kingdom. This spiritual war we’re infused into as humans constrained by Time and physics (Ephesians 6) is between the Father and His former chief cherub angel we’ve come to know as Satan (Luke 10:18); the Father is the Strategist and the “Commander-and-Chief,” the Son is the Warrior (John 3:35); the Spirit is Logistics…these three are One-God.
Those who trust in the Father through Jesus as Lord are the Father’s servants, warriors, and our servitude to our God, Father-Son-Spirit, will transcend Time and Eternity in the New Jerusalem.
“And if one can overpower him who is alone, two can resist him. A cord of three strands is not quickly torn apart.” Ecclesiastes 4:12 (NASB)
