There is a phrase in the Book of Mormon: Another Testament of Jesus Christ that is used several times, it is the phrase "not many years." In the Book of Mormon the Nephite's when listening to the teaching of the prophets and doing the things that they should be doing receive blessings and gain favor in the sight of the Lord, "not many years" show's how quickly things can turn. For example, "Thus had they become weak, because of their transgression, in the space of not many years." Helaman 4:26
We as people just like the Nephite's have the same problem. We may be doing good and the Lord will bless us for all our good, but it can be something little that quickly turns our tide from good to bad. For in the space of "not many years" we can fall into iniquity. But thanks to the wonderful plan that our Heavenly Father and Jesus Christ have come up with we can be forgiven. "The Gospel of Jesus Christ is a gospel of transformation" -Joseph B. Wirthlin. The Nephite's soon realized that they had been doing wrong, "..they saw that the Lamanites were exceedingly more numerous than they, and except they should cleave unto the Lord their God they must unavoidably perish." Helaman 4:25. I know that as we learn from the Book of Mormon that we can be forgiven and that although we fall and sometimes in the space of "not many years" God still loves us and through the Atonement of Jesus Christ we an be forgiven.
