Encyclopedia of Mormonism, pg. 745; “Those who receive the gospel and join The Church of Jesus Christ of Latter-day Saints have power given them to become the sons of God. (D. & C. 11:30; 35:2; 39:1-6; 45:8; John 1:12.) Sonship does not come from church membership alone, but admission into the Church opens the door to such high status, if it is followed by continued faith and devotion. (Rom. 8:14-18; Gal. 3:26-29; 4:1-7.) The sons of God are members of his family and, hence, are joint-heirs with Christ, inheriting with him the fulness of the Father. (D. & C. 93:17-23.) Before gaining entrance to that glorious household, they must receive the higher priesthood (Moses 6:67-68), magnify their callings therein (D. & C. 84:33-41), enter into the new and everlasting covenant of marriage (D. & C. 131:1-4; 132), and be obedient in all things. (Doctrines of Salvation, vol. 2, pp. 8-9, 37-41, 59, 64-65.) Those who become the sons of God in this life (1 John 3:1-3) are the ones who by enduring in continued righteousness will be gods in eternity. (D. & C. 76:58.)”
Romans 8:14; “For as many as are led by the Spirit of God, they are the sons of God.”
The Bible NEVER says that we’ll become gods in eternity.
The Bible also NEVER says we have to join a certain religion to become sons of God.
