'Mental' in the Bible

Listen carefully: I have given you authority [that you now possess] to tread on serpents and scorpions, and [the ability to exercise authority] over all the power of the enemy (Satan); and nothing will [in any way] harm you.

For I wrote to you out of great distress and with an anguished heart, and with many tears, not to cause you sorrow but to make you realize the [overflowing] love which I have especially for you.

and be continually renewed in the spirit of your mind [having a fresh, untarnished mental and spiritual attitude],

For the love of money [that is, the greedy desire for it and the willingness to gain it unethically] is a root of all sorts of evil, and some by longing for it have wandered away from the faith and pierced themselves [through and through] with many sorrows.

But solid food is for the [spiritually] mature, whose senses are trained by practice to distinguish between what is morally good and what is evil.
