'Truths' in the Bible

And my language and the Message that I proclaimed were not adorned with persuasive words of earthly wisdom, but depended upon truths which the Spirit taught and mightily carried home;

But in dealing with truths hitherto kept secret we speak of God's wisdom--that hidden wisdom which, before the world began, God pre-destined, so that it should result in glory to us;

Of these we speak--not in language which man's wisdom teaches us, but in that which the Spirit teaches--adapting, as we do, spiritual words to spiritual truths.

As for us Apostles, let any one take this view of us--we are Christ's officers, and stewards of God's secret truths.

Now I commend you for remembering me in everything, and because you hold fast truths and practices precisely as I have taught them to you.

For he who speaks in an unknown tongue is not speaking to men, but to God; for no one understands him. Yet in the Spirit he is speaking secret truths.
