"All in God" or "God is all in all" is a profound theological concept, especially from 1 Corinthians 15:28, meaning God's supreme rule, presence, and purpose permeate everything, with all creation ultimately subject to Him, signifying His ultimate sovereignty and glory filling all existence after all opposition is overcome. It reflects His encompassing power, with "from Him, through Him, and to Him are all things" (Romans 11:36).
Key Meanings:
Supreme Authority: God's authority extends over every ruler, power, and even death, bringing everything under His control.
All-Encompassing Presence: God isn't just in things, but is the controlling factor and source holding all things together (Colossians 1:17).
Ultimate Purpose: The goal is for God's glory to fill everything, with Christ submitting to the Father so God becomes supreme over everything, everywhere.
Biblical Context:
1 Corinthians 15:28: "When all things are subjected to him, then the Son himself will also be subjected to him who subjected all things to him, that God may be all in all".
Romans 11:36: "For from Him and through Him and to Him are all things. To Him be glory forever. Amen".
Ephesians 4:6: "one God and Father of all, who is over all and through all and in all".
In essence, it's the declaration that God is the beginning, the sustainer, and the final end-goal of all creation, with nothing outside His sovereign purpose and presence.
