Anything worthwhile requires much diligence. This is especially true for living the Gospel. It is not always easy to do the things we are asked, but there are many blessings in store for those who remain diligent.
In the Book of Mormon, the prophet Mormon writes:
"And now, my beloved son, notwithstanding their hardness, let us labor diligently; for if we should cease to labor, we should be brought under condemnation; for we have a labor to perform whilst in this tabernacle of clay, that we may conquer the enemy of all righteousness, and rest our souls in the kingdom of God. " (Moroni 9:6)
"We become what we want to be by consistently being what we want to become." -Elder Richard G. Scott
Be diligent to the end.
