Take a rare phrase (faith of Jesus)
We see how reliance upon other books of men to know the truth of God, rather than trusting only in the Book of God, leads to discounting as to rarely mentioned the only faith of God that saves by Jesus Christ. So much so, that a great reader of such books had not even heard of such a thing as the faith of Jesus Christ, until told to look for it in the Bible.
The faith of Jesus may be rare in the world, but is the only faith known in heaven, and saves on earth.
And the rarely written faith of Jesus in Scripture, is the all important Scripture of salvation and justification with God.
The faith of Jesus Christ may be rarely written in Scripture, but not the abundance of Scriptures for salvation of the Lord.
The Word was God is even more rare, and said only once. And yet without God the Word being made flesh, dying on a cross, and rising again from the dead, there would be no faith of man on earth toward God to save from sin.
There would still be much faith among men to live as they will on earth, but not any faith of Jesus Christ to live forever.
The importance of God's word is not rated by how many times He says it in Scripture...
and create a doctrine that says salvation is by Jesus' faith, not ours.
And so, Jesus faith is His, not yours. And any doctrine of Jesus' faith is not the doctrine of your faith. And yet, the only doctrine of Christ by Scripture, is by the faith of Jesus Christ.
Act 24:24And after certain days, when Felix came with his wife Drusilla, which was a Jewess, he sent for Paul, and heard him concerning the faith in Christ.
Rom 1:5By whom we have received grace and apostleship, for obedience to the faith among all nations, for his name:
Rom 3:3For what if some did not believe? shall their unbelief make the faith of God without effect?
The faith of God is the faith in Christ that saves, and is called the faith of Jesus Christ, not ours.
Eph{2:8} For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
The gift of the faith toward God that saves, is that of Jesus Christ, not of ourselves. The faith of ourselves is faith in ourselves.
And the sinners' own faith is to sin more. Jesus' faith is to sin not. The faith of sinners is to be saved in sins. The faith of Jesus Christ is to be saved from sinning.
There is a world of difference between the common faith of sinners, and the rare faith of Jesus Christ:
Isa 55:8 For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe. (1 Co 1:21)
Those who believe in Jesus Christ, only do so by the gift of His faith, through the preaching of His faith in God.
Gal 3:22But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
Which is only given by grace through repentance of our own sins, will, and faith in and of ourselves.
Heb {6:1} Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
Tusting Christ (i.e., "faith in Christ") is a human ability that all people possess (Ro 10:8)
2Pe 1:1Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ:
We must obtain the faith of Jesus Christ, not by man's power of understanding, but by hearing of the gospel of His faith to save from sin. The faith of Jesus Christ is precious on earth, because it is so rare.
No sinner by understanding, has any faith to be saved from their own sins and trespasses against God and His Christ.
Pro 3:5Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Nor lean to thine own faith.
Rom 10:8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
The promise of Scripture is only to hearers of the word. Not to hearers of the world. The faith of the man Jesus Christ is not the faith nor understanding of the world.
Rom 10:17So then faith cometh by hearing, and hearing by the word of God.
Only them hearing and recieving the faith of Jesus Christ, can be saved and justified by the faith of Jesus Christ.
and it is the one thing people must do in order for God to save them from eternal damnation (Jn 3:16, et. al.).
Those who use their ability to posses their own understanding and faith, are not recieving anything from the Lord, but only from and by themselves.
Eph{2:8} For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
We don't do anything to be saved by Jesus Christ, other than to repent and recieve His faith toward God unto salvation of the soul.
We see here how errors against the truth of Scripture are made by preaching one's own understanding of faith, and not by preaching the rare faith of Jesus Christ in Scripture, that has the only rare power of God to save the soul from sinning against Him.
1Co 13:2And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
