The Lord explained to the brother of Jared that blessings had come to his people as a result of prayers offered over a long time. Enduring obedience coupled with frequent and persistent prayers is powerful. In an 1839 discourse in Commerce, Illinois, the Prophet Joseph Smith taught: “God is not a respecter of persons, we all have the same privilege. Come to God weary him until he blesses you &c we are entitled to the same blessings” ([recorded in Willard Richards Pocket Companion, 78–79] cited in The Words of Joseph Smith: The Contemporary Accounts of the Nauvoo Discourses of the Prophet Joseph, comp. Andrew F. Ehat and Lyndon W. Cook [1980], 15).
President Spencer W. Kimball (1895–1985) similarly taught that we must put great effort into our prayers and that we must pray frequently:
“Do you get answers to your prayers? If not, perhaps you did not pay the price. Do you offer a few trite words and worn-out phrases, or do you talk intimately to the Lord? Do you pray occasionally when you should be praying regularly, often, constantly? Do you offer pennies to pay heavy debts when you should give dollars to erase that obligation?
“When you pray, do you just speak, or do you also listen? Your Savior said, ‘Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.’ (Rev. 3:20.)
“… Should we ever fail to get an answer to our prayers, we must look into our lives for a reason” (“Prayer,” New Era, Mar. 1978, 17).
