Re: The Mind of GOD.
Perhaps what is meant is the Sword of the Spirit, as in the use of God's Word to combat evil?
I want to add that the teachings of Jesus were chosen very carefully according to the audience and how much they could understand, or be responsible for. Jesus taught a lot of things that must be seen in the context of perfect spiritual maturity. He did not compromise His message so babies could handle it: as He said, "Be perfect even as your Father in Heaven is perfect . . ."
