"I long have been impressed with the truth that meaningful prayer requires both holy communication and consecrated work. Blessings require some effort on our part before we can obtain them, and prayer, as 'a form of work, . . . is an appointed means for obtaining the highest of all blessings' (Bible Dictionary, "Prayer," 753). We press forward and persevere in the consecrated work of prayer, after we say 'amen,' by acting upon the things we have expressed to Heavenly Father. Asking in faith requires honesty, effort, commitment, and persistence."
