Due to a lack of understanding the translators of the ‘modern’ translations (e.g., NKJV, NASB, NIV, ESV) have made significant changes in your Bible when compared to the text of the KJV, Sadly, due to these changes many believers are plagued by these vast misinterpretations of Scripture, causing them to miss out on the blessings of the “truth” Scripture is meant to convey. One such example is what is discussed in this below.

Note the significance of the seeming simple changes whereby the words “faith of Christ” being changed to “faith in Christ.”

King James Version - Galatians 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of (Greek “ek,” meaning “out from and with”) the Son of God, who loved me, and gave himself for me.

This is the literal faith of Christ Himself as He flows faith from our regenerated spirit into our soul’s mind.

Paul here above says “I live… by the faith OF the Son of God,” the faithful One, the One who is my new life. I am trusting in Him, His Life, with His faith and His faithfulness, to be the faithful One in me as the One who is able to live the Christian life in me, as the new me. My dependence is on Him, so I cling to and trust and rely upon Him.

Here below in the NIV, as typical of most modern translations, the translators ignore the Greek word “ek” which is correctly translated “of” in the KJV; “ek” means “from and with Him” – “faith of (or from and with) the Son of God.” The NIV, NASB, etc, mis-translators have consistently placed the monkey on my weak back of believers to have enough faith for successful living. We then would have to live by our own weak faith IN Him. If my faith is weak, I fail and it is my fault; then I am self-condemned because my life success as a Christian depends upon my own vacillating level of faith in Christ.

NIV - Galatians 2:20 I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith IN the Son of God, who loved me, and delivered Himself up for me.

Below Cornelius Stam offers his thoughts on this matter.

"...the righteousness of God... by [the] faith of Jesus Christ, unto all and upon all them that believe" (Rom. 3:22).

Note, the Apostle Paul here does not refer to faith in Christ, but the faith of Christ. Nor does he refer to what Christ believed, but rather to His worthiness to be believed, His fidelity, His trustworthiness.

We must not forget that faith is a reciprocal matter; it is two-sided.

One side is objective; it believes in another. The other is subjective; it is a trustworthy character. One refers to what a person does; the other to what he is. If I have faith in you, you should keep faith with me; you should be trustworthy.

Seven times in St. Paul's epistles he refers to "the faith of Christ" and each time his purpose is to emphasize our Lord's worthiness of our complete confidence. That he does not refer to our faith in Christ is evident on the surface in each case. In the passage above he declares that the righteousness of God, which is "by the faith of Christ," is conferred "upon all them that believe" so, here then is our faith in Him, as was generated by “the Spirit of life in Christ Jesus.”

In Gal. 3:22 he states that "the Scripture hath concluded all under sin, that the promise, by faith of Jesus Christ, might be given to them that believe." Here again, we believe because He is worthy of our confidence.

In Phil. 3:9, the Apostle expresses his desire for a righteousness not of his own, "but that which is through the faith of Christ" adding, "the righteousness which is of God by faith." Here's man's faith again! He has faith in Christ because Christ is completely faithful, completely worthy to be believed in. He paid the full penalty for our sins and is now in heaven dispensing the merits of Calvary - riches of grace, mercy and forgiveness.

But remember, "the faith of Christ" always precedes our faith in Christ. What good would it do us to believe in Him for salvation if He were not wholly to be relied upon for this? But He can be trusted "to save... to the uttermost [all] who come unto God by Him" (Heb. 7:25). This is why Paul could say to the terrified jailor at Philippi: "Believe on the Lord Jesus Christ and thou shalt be saved" (Acts 16:31).”
