The Art of War
Are you a toy soldier? Many Christians are. They playact like they are fierce warriors, but the day of war reveals how much of a warrior they really are. Oftentimes they are not as tough as they seem, or as smart as they seem, or as revelatory as they seem. The day of war is a day of revelation: who is a paper tiger, who is a battle-hardened veteran, who is in basic training, who is somewhere in-between.
If you are not combat credible (an important term), unhealthy people will not be deterred or discouraged from attacking you. If you are not combat credible, demons will not be deterred from attacking you. If you are not combat credible, the environment will shape you instead of you shaping the environment. You do not have to be a toy soldier, or an expendable footsoldier, or an amateur! However, to go from awkward basic training to battle-hardened veteran who wins consistently, one must learn the art of war. Warcraft. Military doctrine. War-making and war-winning concepts.
This is precisely what the Word of God says to us.
