1 And I, brethren, when I came to you, came not with excellencie of speech, or of wisedome, declaring vnto you the testimony of God.
2 For I determined not to know any thing amōg you, saue Iesus Christ, and him crucified.
3 And I was with you in weakenesse, and in feare, and in much trembling.
4 And my speech, and my preaching was not with entising words of mans wisedome, but in demonstration of the Spirit, and of power:
5 That your faith should not stand in the wisdome of men, but in the power of God.
1 Cor 2:1-5
