I do not disagree with that, but you said that 'faith' is permanent. It is not!@amadeus Good verses there, indeed.
I was thinking more of the Parable of the Sower, Matthew 13.30, where the fruit born of the seed sown in good ground is permanent: "But he that received seed into the good ground is he that heareth the word, and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty."
Faith is the Way God provided for men to travel to the Light. The Light is permanent. That road will be gone when it is no longer needed when we have each finished our course:
"But when that which is perfect is come, then that which is in part shall be done away." I Cor 13:10
That which is perfect, is that which is complete. When each of us is complete in the Body of Christ then we are at the "face to face" seeing even as He sees. No more through a glass darkly, no more faith. Then it is finished for us as it was finished for Jesus on the cross. Then we see clearly, and we know as He knows! When we are there then...
