What does Deuteronomy say about things once they are revealed?
Deuteronomy teaches that once things are revealed, they belong to us, which means we better believe it. This principle applies to the mystery Paul reveals: formerly hidden truths, now made known, become our possession and our responsibility to believe. This underscores the need to believe revealed truth.
Les explains that Deuteronomy establishes a principle: once something is revealed, it belongs to us, so we had better believe it. In Ephesians 3, Paul writes about the mystery of Christ, which in other ages was not made known to the sons of men as it is now revealed. Les points out that these things Paul reveals were never made known before, and he makes double sure we understand that. The specific segment of the mystery in verse six is that Gentiles should be fellow heirs, of the same body, and partakers of His promise in Christ—not by Judaism or the Mosaic law, but by Christ and His finished work. Les asks whether the Old Testament ever spoke of Gentiles becoming one with Christ or with the God of Abraham, emphasizing how new this revelation is. The application is that once revealed, these truths belong to us, meaning we better believe them.
