'Secrets' in the Bible

Think of us as servants of the Messiah and as servant managers entrusted with God's secrets.

If I have the gift of prophecy and can understand all secrets and every form of knowledge, and if I have absolute faith so as to move mountains but have no love, I am nothing.

For the person who speaks in a foreign language is not actually speaking to people but to God. Indeed, no one understands him, because he is talking about secrets by the Spirit.
