I Corinthians 13:8

never faileth--never is to be out of use; it always holds its place. shall fail . . . vanish away--The same Greek verb is used for both; and that different from the Greek verb for "faileth." Translate, "Shall be done away with," that is, shall be dispensed with at the Lord's coming, being superseded by their more perfect heavenly analogues; for instance, knowledge by intuition. Of "tongues," which are still more temporary, the verb is "shall cease." A primary fulfilment of Paul's statement took place when the Church attained its maturity; then "tongues" entirely "ceased," and "prophesyings" and "knowledge," so far as they were supernatural gifts of the Spirit, were superseded as no longer required when the ordinary preaching of the word, and the Scriptures of the New Testament collected together, had become established institutions.

Here the apostle goes on to commend charity, and show how much it is preferable to the gifts on which the Corinthians were so apt to pride themselves, to the utter neglect, and almost extinction, of charity. This he makes out, I. From its longer continuance and duration: Charity never faileth. It is a permanent and perpetual grace, lasting as eternity; whereas the extraordinary gifts on which the Corinthians valued themselves were of short continuance. They were only to edify the church on earth, and that but for a time, not during its whole continuance in this world; but in heaven would be all superseded, which yet is the very seat and element of love. Prophecy must fail, that is, either the prediction of things to come (which is its most common sense) or the interpretation of scripture by immediate inspiration. Tongues will cease, that is, the miraculous power of speaking languages without learning them. There will be but one language in heaven. There is no confusion of tongues in the region of perfect tranquility. And knowledge will vanish away. Not that, in the perfect state above, holy and happy souls shall be unknowing, ignorant: it is a very poor happiness that can consist with utter ignorance. The apostle is plainly speaking of miraculous gifts, and therefore of knowledge to be had out of the common way (see Co1 14:6), a knowledge of mysteries supernaturally communicated. Such knowledge was to vanish away. Some indeed understand it of common knowledge acquired by instruction, taught and learnt. This way of knowing is to vanish away, though the knowledge itself, once acquired, will not be lost. But it is plain that the apostle is here setting the grace of charity in opposition to supernatural gifts. And it is more valuable, because more durable; it shall last, wh…

13:8-13 Love, in contrast to spiritual gifts, will last forever. 13:8 Love will last forever, because God is love (cp. 1 Jn 4:7-12, 16).
