Fear is not biblical. Fear is lack of Faith. The opposite of fear is Trust. 

Spiritual Warfare

Jesus Christ, Matt 10:34 Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword; meaning: you have to make a choice and you cannot serve two masters. 

Army of God

Daniel 10:13 'But the prince of the kingdom of Persia withstood me but, lo, Michael, one of the chief princes, came to help me'. Michael also appeared to Joshua as he prepared to lead the Israelites in battle at Jericho.

God Favors the Brave

God didn't call you to a playground but a battle ground. Suit up! The greatest archangel is a warrior. The human that God called a 'man after my own heart' was David the warrior (Acts 13:22). God needs you to help fight the fight.
