1 Corinthians 4
1 Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God.
2  Moreover it is required in stewards, that a man be found faithful.
3 But with me it is a very small thing that I should be judged of you, or of man’s judgment: yea, I judge not mine own self.
4 For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.
5 Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
1 Cor.4:1-5

1 Corinthians 1
14 I thank God that I baptized none of you, but Crispus and Gaius;
15 Lest any should say that I had baptized in mine own name.
16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
1 Cor. 1:14-19
