Deuteronomy 20:2-4 When you are about to go into battle, the priest shall come forward and address the army. (Just as a priest was appointed to speak to the army of God to encourage them and exhort them and instruct them, to focus them on their Commander instead of on the enemy, so we, when faced with battle, have to stand as God's appointed priest for the warfare that lies before us. As the priest of war, we stand in God's promises, in His truth, to exhort ourselves and others in the Word through which we gain our courage and instruction.) He shall say: "Hear, Israel: Today you are going into battle against your enemies. Do not be fainthearted or afraid; do not panic or be terrified by them. (The Lord warns His people this fearsome enemy army that presently inhabited the Promised Land will attempt to make himself appear formidable to God's people, just as he continues to do to us today, in every way he can, by the flash of his sword and shield, by the clash of the chariots arrayed against the people, by the sound of the horses upon which he is mounted, and by his shouts and the sound of his trumpet call to battle. In every way, the enemy will appear unbeatable. The enemy's tactics, though, perhaps, different today, can be just as forceful and daunting to us, and this is the very reason and the exact time when we have to take our focus off what our eyes can see and look to the Lord Who is above all the forces of darkness, the One Who overcomes the devices of the enemy with the breath of His nostrils. The Lord calls us to put aside fear and panic and to stand in His protection and armor.) For the Lord your God is the One Who goes with you to fight for you against your enemies to give you victory."
(No matter what we fight against today, the Lord God Almighty has already defeated any enemy we face. Rather than fighting to gain victory, we have to know that we fight from a place of victory already attained through Christ's finished work at the cross.)
