AUV(i)
12 But we [apostles] did not receive the spirit of the world [i.e., human wisdom. See verse 6], but the Holy Spirit from God, so that we could understand what was freely given to us from God [i.e., the gift of inspiration. See verses 9-10].
13 These also are the things we [apostles] speak, not in words taught by human wisdom, but [in words] taught by the Holy Spirit. We use [or, combine] Spirit-taught words to express [or, with] Spirit-given truth.
