1 Ne 10:19 For he that diligently seeketh shall find; and the mysteries of God shall be unfolded unto them

This is one of those transcendent truths contained in the Book of Mormon, Bible (Matt 7:7-8 and Heb 11:6), and the D&C. Draw near unto me and I will draw near unto you; seek me diligently and ye shall find me; ask, and ye shall receive; knock, and it shall be opened unto you. Whatsoever ye ask the Father in my name it shall he given unto you, that is expedient for you (DC 88:63-4).

“The Holy Ghost, as Nephi expresses it in a passage of superlative meaning and beauty, ‘is the gift of God unto all those who diligently seek him, as well in times of old as in the time that he should manifest himself unto the children of men. For he is the same yesterday, today, and forever; and the way is prepared for all men from the foundation of the world, if it so be that they repent and come unto him. For he that diligently seeketh shall find; and the mysteries of God shall be unfolded unto them, by the power of the Holy Ghost, as well in these times as in times of old, and as well in times of old as in times to come; wherefore, the course of the Lord is one eternal round.’(1 Nephi 10:17-19.) In harmony with these words of transcendent beauty are those of latter-day revelation that say simply to every member of the Church: ‘God shall give unto you knowledge by his Holy Spirit, yea, by the unspeakable gift of the Holy Ghost.’ (D&C 121:26.) Such is the promise, and the promise is sure. The sole need on the part of any individual is to comply with the law that entitles him to receive the promised revelation.” (A New Witness for the Articles of Faith, p. 489)
