Paul concedes “I do not claim to have attained [all Truth]” We also can accept many things on faith, i.e., there’s neither a physical body nor a physical universe. Esoteric? Other-worldly? Incomprehensible? Not if you use a top-down approach and start with the answer. God is infinite and so is His entire creation, including you!
In spite of all that seems to be, we live in the spiritual universe of God with Christ as our consciousness.
