Favour = grace= to be saved= faith, to believe in the love our Lord Jesus Christ had to the world to die for all. (the faith of Christ.)
So yes, we do have the faith we see in the scriptures, had by Noah, Abraham, Isaac, Israel, ( Jacob, and Moses, Moses because of hearing the one sent, but not because of a law followed, because favour alone is how one enters the pleasant land, as well testified.
The one the Lord speaks of, to hear him, as the Lord puts all His words into his mouth, and speaks all that He commands him. (SPOKEN IN IS NAME..)
Deuteronomy 18:15 The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;
16 According to all that thou desiredst of the Lord thy God in Horeb in the day of the assembly, saying, Let me not hear again the voice of the Lord my God, neither let me see this great fire any more, that I die not.
17 And the Lord said unto me, They have well spoken that which they have spoken.
18 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
To believe on the Son is to believe on Him who sent Him.
A light come into the WORLD, whosoever believes on Him should not abide in darkness, the Son did not come to judge the WORLD, but to SAVE THE WORLD.
He did not speak of Himself, but of the Father who sent Him, who gave commandment what He should say and speak, HIs commandment is life everlasting, ( BELIEF ON THE SON OF GOD.) so the Son speaks even as the Father said. (of LIFE EVERLASTING.)
The Father confirmed what Moses had said, to hear the one He sent, that THIS IS HIS BELOVED SON, IN WHOM HE IS WELL PLEASED, HEAR YE HIM.
The Son received form the Father glory and honour from that voice, and we are to hear that WORD, to do well to TAKE HEED/HEARKEN, as unto a LIGHT THAT SHINES IN A DARK PLACE, until the day star ARISE in your hearts. ( I am come a light into the world, that whosoever believeth on me should not abide in darkness.)
Hearkening is then by FAITH. It cannot come by commandment of law.
John 12:44 Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me.
45 And he that seeth me seeth him that sent me.
46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.
47 And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world.
48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
Matthew 17:5 While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my
beloved Son, in whom I am well pleased;
hear ye him.
2 Peter 1:17 For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
18 And this voice which came from heaven we heard, when we were with him in the holy mount.
19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
