For no one can lay [any] other foundation than the one which [God] has [already] laid, which is Jesus Christ.

For the person who speaks in a language [supernaturally] does not speak to people, but to God, for no one can understand him [i.e., unless there is an interpreter or it is the person's native language]; he speaks [previously] unrevealed truths under the influence of the Holy Spirit [or "in his spirit"]. [Note: For a correct understanding of this chapter, it must be kept in mind that Paul is addressing a misuse ofthe gift of speaking in languages supernaturally. The Corinthians were doing this in the wrong way and for the wrong purpose].
