Our knowledge in this life remains imperfect, but it is reliable within its limits. Believers trust the witness of their senses, which are subservient to their intelligence. They may occasionally be deceived, but even so they are still better off than those who maintain that the senses can never be trusted.
For we know in part and we prophesy in part, i.e, imperfectly. Ephrem turns it. "We know but little of much;" for the Apostle opposes what is little and imperfect, what we know partly by reason, partly by prophecy, to what is perfect (ver10), i.e, to the perfect vision and knowledge of God in himself, and of all things in God. It is certainly true that the whole being of God, and all His attributes and perfections, we do not know in this life, but all the blessed know them, and they alone. He proves this from the example of a boy, who grows both in age and knowledge. For the blessed are in knowledge as men, and we in it as boys. Again, our theological knowledge, though it is certain, is yet hidden and obscure; it leans on faith, and for that reason alone it is in part or imperfect. The blessed, however, know all things clearly and intuitively, nay, they see and behold face to face.
And we, while upon the earth, as Paul also declares, "know in part, and prophesy in part.".
But if any lover of strife contradict what I have said, and also what the apostle affirms, that "we know in part, and prophesy in part".
For these are animal bodies, that is,
We know in part, and we prophesy in part. But when that which is perfect has come, then that which is in part shall be done away.
It is not therefore knowledge that is done away, but the circumstance that our knowledge is in part. For we shall not only know as much but even a great deal more. But that I may also make it plain by example; now we know that God is every where, but how, we know not. That He made out of things that are not the things that are we know; but of the manner we are ignorant. That He was born of a virgin, we know; but how, we know not yet. But then shall we know somewhat more and clearer concerning these things. Next he points out also how great is the distance between the two, and that our deficiency is no small one.
