For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline. (NIV)

For God did not give us a spirit of timidity (of cowardice, of craven and cringing and fawning fear), but [He has given us a spirit] of power and of love and of calm and well-balanced mind and discipline and self-control. (AMP)

For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind. (KJV)
