2 Nephi 32:8-9
And now, my beloved brethren, I perceive that ye ponder still in your hearts; and it grieveth me that I must speak concerning this thing. For if ye would hearken unto the Spirit which teacheth a man to pray ye would know that ye must pray; for the evil spirit teacheth not a man to pray, but teacheth him that he must not pray.
But behold, I say unto you that ye must pray always, and not faint; that ye must not perform any thing unto the Lord save in the first place ye shall pray unto the Father in the name of Christ, that he will consecrate thy performance unto thee, that thy performance may be for the welfare of thy soul.
Prayer is man’s means of communicating with his Heavenly Father, the Almighty, Creator of heaven and earth. Only the deceived and the fool refuse to pray. An urgent need today is for more prayer–secret, individual prayer; family prayer; prayer in organizations, associations, and meetings generally, and in schools, and in government bodies. People of all nations need more prayer. We need to be on our knees. (Ezra Taft Benson, The Teachings of Ezra Taft Benson [Salt Lake City: Bookcraft, 1988], 421 – 422.)
