Jamieson, Fausset and Brown on 1 Corinthians 1:7

7. ye come behind--are inferior to other Christians elsewhere [Grotius].

in no gift--not that all had all gifts, but different persons among them had different gifts (1Co 12:4, &c.).

waiting for ... coming of ... Christ--The crowning proof of their "coming behind in no gift." Faith, hope, and love, are all exercised herein (compare 2Ti 4:8; Tit 2:13). "Leaving to others their MEMENTO MORI (remember death), do thou earnestly cherish this joyous expectation of the Lord's coming" [Bengel]. The Greek verb implies, "to expect constantly, not only for a certain time, but even to the end till the expected event happens" (Ro 8:19, [Tittmann, Greek Synonyms of the New Testament]).
