The word and power of God

1. Alma 17: 17
     17 Therefore they separated themselves one from another, and went forth among them, every man alone, according to the word and power of God which was given unto him.
2. Alma 53: 10
     10 And now behold, I have somewhat to say concerning the people of Ammon, who, in the beginning, were Lamanites; but by Ammon and his brethren, or rather by the power and word of God, they had been converted unto the Lord; and they had been brought down into the land of Zarahemla, and had ever since been protected by the Nephites.
