No, I am not making it up. Search the word out for yourself in the Textus Receptus Greek, and not the Westcott and Hort Greek. "Metanoeo"
It means to have another mind. Now go find out how that is so in 1 Cor. 2:16 and Rom. 8:9- KJV.
If you are in Christ, you should know what I'm talking about.
Even metanoia as a compound is the "after-mind", if I remember correctly. The result of an exchanged mind. We start with the mind of the flesh, but we receive the truth of Jesus, and exchange the mind of the flesh for the mind of Christ.
And then, we need to become self-aware - the true self-awareness, that we do in fact now have the mind of Christ, and reject everything that does not conform.
Much love!
Mark
