John 6:56 - Coke's Commentary on the Holy Bible

Dwelleth in me, and I in him,— "We are most intimately connected together in the closest union, communion, and friendship; and therefore whatever blessings I can bestow, whether by my own power, or by my intercession with the Father, or by the influences of my Spirit; my faithful friends shall enjoy them in full perfection." The expression of persons dwelling in each other, occurs frequently in St. John's writings, and denotes the closest union of affections and interests: wherefore, according to the grand figure made use of by St. Paul, it signifies that he who truly believes on Christ, is so united to him, as to be a member of his body, and consequentlya partaker with him of his life, and, if faithful unto death, of his glory, and of all the happiness which he himself enjoys, or is able to communicate.
