The other day a man asked me a very interesting question.
"How do you know that Jesus is your Savior?"
I thought a lot about that and then applied that questions to other things. Like how do I know that the Church of Jesus Christ of Latter-day Saints is Christ's church on the earth again. How do I know that the Book of Mormon is true? How do I know that there is a prophet on the earth again? How do I know?
Nephi also teaches us how we can know certain things of God. Here is a converstaion that he had with his brothers.
"And I said unto them: Have ye inquired of the Lord?
And they said unto me: We have not; for the Lord maketh no such thing known unto us.
Behold, I said unto them: How is it that ye do not keep the commandments of the Lord? How is it that ye will perish, because of the hardness of your hearts?
Do ye not remember the things which the Lord hath said?—If ye will not harden your hearts, and ask me in faith, believing that ye shall receive, with diligence in keeping my commandments, surely these things shall be made known unto you."
One last thing, I know that you can come to know these truths for yourself. All you have to do is ask God with a open heart and then be willing to act. Be willing to take that step on the floor. I know it will change your life and make it better than better.
