John 14:20 (NRSV) — Theosis

Basil the Great

Just as when a sunbeam falls on bright and transparent bodies, they themselves become brilliant too, and shed forth a fresh brightness from themselves, so souls wherein the Spirit dwells, illuminated by the Spirit, themselves become spiritual, and send forth their grace to others. Hence comes foreknowledge of the future, understanding of mysteries, apprehension of what is hidden, distribution of good gifts, the heavenly citizenship, a place in the chorus of angels, joy without end, abiding in God, the being made like to God, and, highest of all, the being made God.

. . . created he them; and blessed them, and called their name Adam, in the day when they were created.

Brigham Young

Now those men, or those women, who know no more about the power of God, and the influences of the Holy Spirit, than to be led entirely by another person, suspending their own understanding, and pinning their faith upon another’s sleeve, will never be capable of entering into the celestial glory, to be crowned as they anticipate; they will never be capable of becoming Gods.
