1 Corinthians 13:9-10

Verse 9. For we know in part. Comp. 1Cor 12:27. This expression means, "only in part;" that is, imperfectly. Our knowledge here is imperfect and obscure. It may, therefore, all vanish in the eternal world amidst its superior brightness; and we should not regard that as of such vast value which is imperfect and obscure. Comp. 1Cor 8:2. This idea of the obscurity and imperfection of our knowledge, as compared with heaven, the apostle illustrates (1Cor 13:11) by comparing it with the knowledge which a child has, compared with that in maturer years; and (1Cor 13:12) by the knowledge which we have in looking through a glass--an imperfect medium--compared with that which we have in looking closely and directly at an object without any medium.

And we prophesy in part. This does not mean that we partly know the truths of religion, and partly conjecture or guess at them; or that we know only a part of them, and conjecture the remainder. But the apostle is showing the imperfection of the prophetic gift; and he observes, that there is the same imperfection which attends knowledge. It is only in part; it is imperfect; it is indistinct, compared with the full view of truth in heaven; it is obscure; and all that is imparted by that gift will soon become dim and lost, in the superior brightness and glory of the heavenly world. The argument is, that we ought not to seek so anxiously that which is so imperfect and obscure, and which must soon vanish away; but we should rather seek that love which is permanent, expanding, and eternal.

(a) "in part" 1Cor 8:2
Verse 10. But when that which is perfect is come. Does come; or shall come. This proposition is couched in a general form. It means that when anything which is perfect is seen or enjoyed, then that which is imperfect is forgotten, laid aside, or vanishes. Thus, in the full and perfect light of day, the imperfect and feeble light of the stars vanishes. The sense here is, that in heaven--a state of absolute perfection--that which is "in part," or which is imperfect, shall be lost in superior brightness. All imperfection will vanish. And all that we here possess that is obscure shall be lost in the superior and perfect glory of that eternal world. All our present unsatisfactory modes of obtaining knowledge shall be unknown. All shall be clear, bright, and eternal.

(b) "But when" 1Jn 3.2
