2 Nephi 31:19

In this verse, it says, "...for ye have not come thus far save it were by the word of Christ with unshaken faith in him, relying wholly upon the merits of him who is mighty to save." This verse really made an impression on me, because I realized that Christ really is the only reason that we have anything that we have, and he is the only reason that we are able to progress and become better in this life. We have "come thus far" by having strong faith in him, and obeying his words. It's very comforting to know that he is always there for us, and he wants us to keep getting better and better, and to do it through faith in him and obedience to his words.
