[Heber J. Grant]
[Fast meeting in temple] [Joseph F. Smith] Referred to the fidelity and faithfulness of those who had entered plural marriage. Said the sisters who had been true to their covenants would have a glory as fadeless as the glory of God. Said that plural marriage had been a great trial to those who had entered into that relation, but those who had honored it as God Almighty had revealed the principle would be blessed of God. The principle had come from God and so long as God gave him words to speak he should defend it. Said those who would oppose the principle would lose the Spirit of the Lord. Gave the Saints to understand however, that at the present time there was no opportunity for any person to practice this principle, notwithstanding that it was from our Heavenly Father.
