Faith in what? Perfect faith simply means to put your full faith and trust in Christ alone. In that regard it is perfect faith, yes. And yes it is required.
>>and for this perfection to merit your salvation.<<
Woooops! No "meriting" incurred. Only submission and acceptance that Jesus did it all. It was even the faith of Jesus given us by God whereby we believe.
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 the Son of God, who loved me, and gave himself for me.”
Philippians 3:9 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
It's not even our own faith but the faith of Christ through us whereby we are saved. No "merit" on our part.
But this is the conundrum, NO act of ours will be perfect, NONE on this mortal coil, NONE NONE NONE. Not even faith...
Do YOU have this perfect faith? Are you SURE? (David: Who can discern his own errors?) If there is some flaw in it, no matter how little, how about looking to YOUR knitting before lecturing THE REST OF US.
I rather rely on this, that my flawed faith is placed in a perfect Savior, who has already provided to overcome the problems.
