Rom 12:3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
Acts 14:27 And when they were come, and had gathered the church together, they rehearsed all that God had done with them, and how he had opened the door of faith unto the Gentiles.
Rom 10:6 But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:)
If righteousness is “of faith” would you also say you earn your own righteousness? Since all Christians should say that salvation is not by works then we must also say that faith is not by our works lest we should boast.
If we must muster up our own faith then justification is by works and again we know that is not correct.
Christ's faith was so strong that He was willing to die for our sins, KNOWING that God the Father would raise Him from the dead once the penalty had been paid.
This is the faith OF Christ that is imparted to us by God. We are so certain that the penalty for our sins was paid in full by Christ that we are willing to die, knowing we WILL be raised from the dead.
This is not faith we can muster by our own works, but the faith of Christ that is imparted to us. Just as salvation is imparted to us by God in His grace.
“If righteousness is “of faith” would you also say you earn your own righteousness? Since all Christians should say that salvation is not by works then we must also say that faith is not by our works lest we should boast.”
Again, read the scriptures. There is only one time that faith is described as a ‘work’, and then it is commanded by Jesus for us to do:
26 Jesus answered them and said, “Truly, truly, I say to you, you seek Me, not because you saw signs, but because you ate of the loaves and were filled. 27 Do not work for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give to you, for on Him the Father, God, has set His seal.”
28 Therefore they said to Him, “What shall we do, so that we may work the works of God?” 29 Jesus answered and said to them, “This is the work of God, that you believe in Him whom He has sent.” - John 6
If you want to say faith is a ‘work’, then it is the ‘work’ required of us.
“Verse 29. This is the work of God. This is the thing that will be acceptable to God, or which you are to do in order to be saved. Jesus did not tell them they had nothing to do, or that they were to sit down and wait, but that there was a work to perform, and that was a duty that was imperative. It was to believe on the Messiah. This is the work which sinners are to do; and doing this they will be saved, for Christ is the end of the law for righteousness to every one that believeth, Romans 10:4.”

“29. The work of God is this. They had spoken of works Christ reminds them of one work, that is, faith; by which he means that all that men undertake without faith is vain and useless, but that faith alone is sufficient, because this alone does God require from us, that we believe For there is here an implied contrast between faith and the works and efforts of men; as if he had said, Men toil to no purpose, when they endeavor to please God without faith, because, by running, as it were, out of the course, they do not advance towards the goal. This is a remarkable passage, showing that, though men torment themselves wretchedly throughout their whole life, still they lose their pains, if they have not faith in Christ as the rule of their life. Those who infer from this passage that faith is the gift of God are mistaken; for Christ does not now show what God produces in us, but what he wishes and requires from us...
...It is idle sophistry, under the pretext of this passage, to maintain that we are justified by works, if faith justifies, because it is likewise called a work First, it is plain enough that Christ does not speak with strict accuracy, when he calls faith a work, just as Paul makes a comparison between the law of faith and the law of works, (Romans 3:27.) Secondly, when we affirm that men are not justified by works, we mean works by the merit of which men may obtain favor with God. Now faith brings nothing to God, but, on the contrary, places man before God as empty and poor, that he may be filled with Christ and with his grace. It is, therefore, if we may be allowed the expression, a passive work, to which no reward can be paid, and it bestows on man no other righteousness than that which he receives from Christ.”
