God has given each of us gifts to be use for his glory. We have to exercise the gifts that God has placed in us. We cannot operate or allow fear to overtake us because God has given us the spirit of authority, love and a sober mind to utilize our gifts to further the kingdom of God. Our purpose is to reach out to a dying world and tell them that Jesus saves.
Wherefore I put thee in remembrance that thou stir up the gift of God, which is in thee by the putting on of my hands. For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind. 1 Timothy 2:6-7
