D&C 98

I don't know why that certain words at time seem to jump off the page.  As the saints in Zion were suffering, the Savior said -

"VERILY I say unto you my friends, fear not, let your hearts be comforted; yea, rejoice evermore, and in everything give thanks;
2 Waiting patiently on the Lord, for your prayers have entered into the ears of the Lord of Sabaoth, and are recorded with this seal and testament—the Lord hath sworn and decreed that they shall be granted.
3 Therefore, he giveth this promise unto you, with an immutable covenant that they shall be fulfilled; and all things wherewith you have been afflicted shall work together for your good, and to my name's glory, saith the Lord."  (Doctrine and Covenants | Section 98:1 - 3)

Sometimes when we begin to think our prayers are not being heard, the Savior promises "your prayers have entered into the ears of the Lord of Sabaoth, and are recorded with this seal and testament".  That is comforting.
