Spencer W. Kimball said, "Prayer is not an optional activity; it is basic to our religion." Prayer is a commandment, just like Sabbath observance, tithing and living the Word of Wisdom.
In numerous places the scriptures tell us to pray always. "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." (2 Ne. 32: 9)
The scriptures also tell us why it is important that we pray always. "Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man." (Luke 21: 36)
Nine times in the Doctrine and Covenants the Lord commands us to pray always as a means of avoiding temptation. To Newel K. Whitney and to all of us, he said, "What I say unto one I say unto all; pray always lest that wicked one have power in you...." (D&C 93: 49-50)
The Lord has blessed us with all that we have. We should willing accept his command and show our gratitude through prayer.
