Seeing then that we have such hope, we use great plainness of speech:
Like they used great plainness of speech, we should speak plainly. We shouldn't speak cryptically, like the Old Testament, according to the letter of the law. We should speak clearly and simply, about Christ.
Application Ephesians 6:19
And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel,
I'll be more assertive when I preach the gospel.
