That these things are true

1. 2 Ne. 25: 20
     20 And now, my brethren, I have spoken plainly that ye cannot err. And as the Lord God liveth that brought Israel up out of the land of Egypt, and gave unto Moses power that he should heal the nations after they had been bitten by the poisonous serpents, if they would cast their eyes unto the serpent which he did raise up before them, and also gave him power that he should smite the rock and the water should come forth; yea, behold I say unto you, that as these things are true, and as the Lord God liveth, there is none other name given under heaven save it be this Jesus Christ, of which I have spoken, whereby man can be saved.
2. Mosiah 2: 41
     41 And moreover, I would desire that ye should consider on the blessed and happy state of those that keep the commandments of God. For behold, they are blessed in all things, both temporal and spiritual; and if they hold out faithful to the end they are received into heaven, that thereby they may dwell with God in a state of never-ending happiness. O remember, remember that these things are true; for the Lord God hath spoken it.
3. Alma 30: 41

     8 And now, behold, I will testify unto you of myself that these things are true. Behold, I say unto you, that I do know that Christ shall come among the children of men, to take upon him the transgressions of his people, and that he shall atone for the sins of the world; for the Lord God hath spoken it.
5. Hel. 7: 29
