When prayer works as it should, we express the feelings of our hearts in simple words. Heavenly Father typically answers by putting thoughts in our minds accompanied by feelings. He always hears the sincere prayer we offer when we pray with a commitment to obey Him, whatever His answer and whenever it comes.
The Lord makes this promise to all who read and pray about the Book of Mormon:
“And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.
“And by the power of the Holy Ghost ye may know the truth of all things” (Moroni 10:4–5).
That promise is sure. Millions of people have tested and proved that wonderful promise about prayer by receiving a blessing that has filled their lives with joy and lasting happiness. That promise applies to all our prayers to know the mind and will of God for us.
