1 Corinthians 3:1, 10-11, 2-9
1 Corinthians 3:1 NASB1995
And I, brethren, could not speak to you as to spiritual men, but as to men of flesh, as to infants in Christ.
1 Corinthians 3:10-11 NASB1995
According to the grace of God which was given to me, like a wise master builder I laid a foundation, and another is building on it. But each man must be careful how he builds on it. For no man can lay a foundation other than the one which is laid, which is Jesus Christ.
