Let this mind be in you, which was also in Christ Jesus.
–Philippians 2:5 (KJV)

And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
–Romans 12:2 (KJV)

The mind, the only instrument
Of truth and love and peace;
And thought, the only action played
To either start or cease.

So care well for the instrument
And music that it makes!
Though Spirit is eternal Life,
It’s thought that gives and takes.

In harmony the mind is tuned
To Heaven’s love and grace;
In discord are the thoughts that bind
And put a Hell in place.

So tune ye well the instrument
Of truth and love and peace!
And play the song of Heaven’s throng,
That makes the mind go free!
