To the remnants of the children of Israel, on a mountain near Jerusalem and amidst the ruins of destruction in the Americas, Jesus preached his gospel as found in the Bible in Matthew 7 and in the Book of Mormon in 3 Nephi 14. It is no surprise that his gospel is the same to all his people.
He taught that we should not judge unrighteously because the same measuring stick we use for another's worth will be used to measure our own. He taught that we should ask, seek and knock--that we should come unto God for all that we need and desire. He taught that the way to God is straight and narrow, meaning there are not many roads back to God, but only one.
He taught that we should beware of false prophets and that we would recognize them by their fruits. In other words our actions speak louder than words. Not everyone who claims to know the Lord will be known of him. Our bad acts speak louder than our good words.
Then Jesus concludes with this most powerful analogy. The wise and foolish man. Let us be wise. Let us make Christ our foundation, the rock upon which our lives are built.
3 Nephi 14
24 Therefore, whoso heareth these sayings of mine and doeth them, I will liken him unto a wise man, who built his house upon a rock—
25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not, for it was founded upon a rock.
26 And every one that heareth these sayings of mine and doeth them not shall be likened unto a foolish man, who built his house upon the sand—
27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell, and great was the fall of it.
(Compare with Matthew 7.)
