Fear is an enemy you cannot afford to entertain in your life.
One of the major things in life that keeps us from achieving and reaching for greater achievements in life is fear.
The fear you making mistakes. Fear of loosing investment. Fear of being in a relationship with the opposite sex because of past disappointment, etc. All these are deceptions from the devil.
God has assured us that no matter where we go and whatsoever we do, we should know that He is with us; for He shall never leave nor forsake us. In 2 Timothy 1:7 we are reminded of the kind of Spirit we have been given.
For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
