'Calm' 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].

But as for you, be clear-headed in every situation [stay calm and cool and steady], endure every hardship [without flinching], do the work of an evangelist, fulfill [the duties of] your ministry.
