Now that we obliterated your ignorance and disdain of how the Bible understands and uses the word "until", let's proceed to eliminate your disdain of Christ's Eternal Reign with the Father.
In 1 Cor 15:24-26, you are confusing Jesus' functional role in the redemption order with ontological subordination (inferiority of nature), which the Scripture everywhere denies. Paul is describing the completion of Jesus’s Mission, after which the perfected kingdom is presented to the Father. The “until” in 1 Cor 15:25 does not imply cessation of reign (just as Christ “reigns until” all enemies fall, but does not stop reigning afterward), but rather indicates the milestone after which His reign is fully consummated. Likewise, the Son “being subjected” in v. 28 refers to the Son’s restored, harmonious filial order after the conquest of evil, not to His nature becoming subordinate. It is the same kind of “subjection” the Son eternally has according to His divine sonship (Jn 5:19–23) and the same relational order in which every knee bows to Him as YHWH (Phil 2:10–11; Isa 45:23). Paul directly contradicts your Arian interpretation by teaching that after the end, the throne of God and of the Lamb is one (Rev 22:1), meaning the Father and the Son share one single divine throne forever. Therefore, 1 Corinthians 15:24–28 describes not the termination of the Son’s kingship, but the final victory of His mediatorial reign, after which His eternal divine kingship continues visibly united with the Father’s, exactly as Scripture declares from beginning to end.
In fact, Scripture repeatedly and explicitly states that Christ’s throne is Eternal, not temporary: “Your throne, O God, is forever and ever” (Ps 45:6-7, applied directly to Jesus in Heb 1:8); “His kingdom will have no end” (Lk 1:33); “They will reign for ever and ever” with the Lamb (Rev 22:3–5). In Hebrews 1, the Father Himself declares the Son’s throne eternal precisely to show His superiority to all creation (Heb 1:8–12), which obliterates any and every Arian heretical interpretation.
