1 Corinthians 1:7

come behind should rather be translated fall short. No comparison with other Churches seems to have been intended.

the coming of our Lord Jesus Christ The word in the original and in the margin of the English version is revelation. But this is not always equivalent to coming. The -revelation of Jesus Christ" unquestionably means (1) the Last Day in such passages as 2 Thessalonians 1:7 and 1 Peter 1:7, and the same is the case with St Luke 17:30. But on the other hand, in passages such as 2 Corinthians 12:1; Galatians 1:12; Galatians 1:16; Galatians 2:2, it means (2) the fuller revelation of the mysteries of God's kingdom; while in Revelation 1:1, it signifies (3) the unfolding of things to come. The second of these three meanings would seem most appropriate here. The testimony of Christ, confirmed originally by the inward witness of the Spirit, receives additional confirmation by the gradual unfolding of things Divine, until the believer, fully grounded in the faith, stands without reproach before Christ at His coming.
