New Defender's Study Bible Notes
2:10 hath revealed. Some of these heavenly glories have, indeed, been revealed to us through the Apostle John, in Revelation 21 and 22.
2:13 the Holy Ghost teacheth. Paul thus claims that his teachings are not really his, but God’s, for their very words are taught by the Holy Spirit. This is a clear claim to divine verbal inspiration of Paul’s own epistles.
