d&c 78: 17 - 19
verily, verily, I say unto you, ye are little children, and ye have not as yet understood how great blessings the Father hath in his own hands and prepared for you;
and ye cannot bear all things now; nevertheless, be of good cheer, for I will lead you along. the kingdom is yours and the blessings thereof are yours, and the riches of eternity are yours.
and he who receiveth all things with thankfulness shall be made glorious; and the things of this earth shall be added unto him, even an hundred fold, yea, more.
