As Son of God

1 And now Abinadi said unto them: I would that ye should understand that God himself shall come down among the children of men, and shall redeem his people.
2 And because he dwelleth in flesh he shall be called the Son of God, and having subjected the flesh to the will of the Father, being the Father and the Son—
3 The Father, because he was conceived by the power of God; and the Son, because of the flesh; thus becoming the Father and Son—
4 And they are one God, yea, the very Eternal Father of heaven and of earth.
5 And thus the flesh becoming subject to the Spirit, or the Son to the Father, being one God, suffereth temptation, and yieldeth not to the temptation, but suffereth himself to be mocked, and scourged, and cast out, and disowned by his people.
6 And after all this, after working many mighty miracles among the children of men, he shall be led, yea, even as Isaiah said, as a sheep before the shearer is dumb, so he opened not his mouth.
7 Yea, even so he shall be led, crucified, and slain, the flesh becoming subject even unto death, the will of the Son being swallowed up in the will of the Father.
8 And thus God breaketh the bands of death, having gained the victory over death; giving the Son power to make intercession for the children of men—
9 Having ascended into heaven, having the bowels of mercy; being filled with compassion towards the children of men; standing betwixt them and justice; having broken the bands of death, taken upon himself their iniquity and their transgressions, having redeemed them, and satisfied the demands of justice. (Mosiah 15)

As Messiah

13 But, behold, ye not only deny my words, but ye also deny all the words which have been spoken by our fathers, and also the words which were spoken by this man, Moses, who had such great power given unto him, yea, the words which he hath spoken concerning the coming of the Messiah.
14 Yea, did he not bear record that the Son of God should come? And as he lifted up the brazen serpent in the wilderness, even so shall he be lifted up who should come.
15 And as many as should look upon that serpent should live, even so as many as should look upon the Son of God with faith, having a contrite spirit, might live, even unto that life which is eternal.
16 And now behold, Moses did not only testify of these things, but also all the holy prophets, from his days even to the days of Abraham.
17 Yea, and behold, Abraham saw of his coming, and was filled with gladness and did rejoice.
18 Yea, and behold I say unto you, that Abraham not only knew of these things, but there were many before the days of Abraham who were called by the order of God; yea, even after the order of his Son; and this that it should be shown unto the people, a great many thousand years before his coming, that even redemption should come unto them.
19 And now I would that ye should know, that even since the days of Abraham there have been many prophets that have testified these things; yea, behold, the prophet Zenos did testify boldly; for the which he was slain.
20 And behold, also Zenock, and also Ezias, and also Isaiah, and Jeremiah, (Jeremiah being that same prophet who testified of the destruction of Jerusalem) and now we know that Jerusalem was destroyed according to the words of Jeremiah. O then why not the Son of God come, according to his prophecy?
21 And now will you dispute that Jerusalem was destroyed? Will ye say that the sons of Zedekiah were not slain, all except it were Mulek? Yea, and do ye not behold that the seed of Zedekiah are with us, and they were driven out of the land of Jerusalem? But behold, this is not all—
22 Our father Lehi was driven out of Jerusalem because he testified of these things. Nephi also testified of these things, and also almost all of our fathers, even down to this time; yea, they have testified of the coming of Christ, and have looked forward, and have rejoiced in his day which is to come.
23 And behold, he is God, and he is with them, and he did manifest himself unto them, that they were redeemed by him; and they gave unto him glory, because of that which is to come. (Helaman 8)
