'Mind' in the Bible

For God did not give us a spirit of timidity or cowardice or fear, but [He has given us a spirit] of power and of love and of sound judgment and personal discipline [abilities that result in a calm, well-balanced mind and self-control].

Remember Jesus Christ [the ever-living Lord who has] risen from the dead, [as the prophesied King] descended from David [king of Israel], according to my gospel [the good news that I preach],

But have nothing to do with foolish and ignorant speculations [useless disputes over unedifying, stupid controversies], since you know that they produce strife and give birth to quarrels.
