God has not given us the spirit of fear, but the spirit of power, of courage and resolution, to meet difficulties and dangers; the spirit of love to him, which will carry us through opposition. And the spirit of a sound mind, quietness of mind. The Holy Spirit is not the author of a timid or cowardly disposition, or of slavish fears. We are likely to bear afflictions well, when we have strength and power from God to enable us to bear them.
2 Timothy 1:7 (New King James Version)
7 For God has not given us a spirit of fear, but of power and of love and of a sound mind.
