Rom 3:22 (KJV) Even the righteousness of God with is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Gal 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 the Son of God, who loved me, and gave himself for me.
Gal 3:22 But the scripture hat concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
Notice that it doesn't say faith 'in' Christ but faith 'of' Christ. "He trusts in God; let Him (the Father) save Him (the Son) now" (Matt 27:43; Psa 22:8) -- Jesus Christ believed and trusted in the Father. So when He came to the scripture, "I'll obey Your word" (Psalm 119) wasn't the vain imaginations of the sinner but rather the framework and vehicle for His faith, the faith of Jesus Christ, to come and redeem sinful humanity. This is explicitly confirmed by the Hebrews 10:9 citation of Psalm 40 - "I come to do Your will, Oh God" etc. The faithful obedience of the Son becomes the gateway to salvation to all who would believe.
And it is the faithful Spirit of this Son who comes into our hearts, crying "Abba, Father!" It is the faith of Christ that inflames our hearts, not our own. Remember that it's no longer we who live but the Spirit of the Son who lives in us, who's guiding us home through repentance and obedience.
Safe to say that Witness Lee looked at the Psalms and missed all this, even though NT usage gave a clear invitation to do so. He had his "God's economy" metric to protect. I argue that by distracting people from God's Christ, and discouraging them from finding the faith of Christ in its pages, Witness Lee's RecV Bible isn't worth the paper it's printed on.
Of course that's merely my view at present, and it may change over time, as my views often do. And the real truth here may be that I'm a vain, quarrelsome person, looking to pick a fight somewhere. If so, and to what extent this is true, I apologize for a wrong spirit.
You know, if Moses was a true and faithful peacemaker, when he saw the Egyptian beating the Hebrew slave, he'd have run up and embraced them both, and healed them, and they'd all sing "Kumbaya" together. Unfortunately it wasn't to be so, at that time. But the faith of Christ is coming, folks. Be embraced and love your neighbor as yourself, even the one who's currently suffering under bad ideas, and causing others to suffer. Because we all fail. "Who has sinned, and I don't burn?"
It seems fitting to leave you with a song:
