I--the preacher: as Co1 2:2 describes the subject, "Christ crucified," and Co1 2:4 the mode of preaching: "my speech . . . not with enticing words," "but in demonstration of the Spirit." weakness--personal and bodily (Co2 10:10; Co2 12:7, Co2 12:9; Gal 4:13). trembling--(compare Phi 2:12). Not personal fear, but a trembling anxiety to perform a duty; anxious conscientiousness, as proved by the contrast to "eye service" (Eph 6:5) [CONYBEARE and HOWSON].
