1 Corinthians 13:9

The reading γάρ, for, is evidently preferable to the δέ, then, of the Byz. The apostle wishes to explain why this doing away shall take place. Prophecy lifts on each occasion only a corner of the veil which covers the plan of God and its final accomplishment. Similarly the isolated acts of spiritual knowledge grasp the truth of salvation only in fragments, and consequently every particular point of the great fact. Even to possess the complete knowledge of one point, the whole would require to be known distinctly. Now this full and only true knowledge is not granted us in the present economy. As to tongues, the apostle does not think it necessary to justify their disappearance. The reason for it is too evident: it is their ecstatic character. The only ground for ecstatic transport is that we are not yet living fully in the reality of the Divine. When we live in God, we are in Him without going out of ourselves. This is why there is no ecstasy in the life of Jesus, at least after His baptism.
