I have no personal experience with military combat in the natural, but I do know that for a battle to be won you must leave the trenches. The trenches do serve a purpose, but there comes a time when you no longer can stay away from the enemy. You must engage!
Some believers think that if they stay in the trenches, hunkered down, they will be safe. They also mistakenly believe that they are called to remain out of the fight, that the kingdom of God need only be expanded from within the walls of the churches, and not in the world, that we don’t have to take ground, nor have the authority to do so. This is all false. We do indeed need to engage our enemy and fight for the kingdom. It is done on the battlefield.
The enemy that we the Ecclesia is fighting is not new to us. He is the one that Jesus declared is beneath our feet, it is his head that we are called to crush, using all authority that has been given us from Christ. The battle has been won according to Scripture, but it demands our agreement with God’s Word.
A soldier does not go into battle with the mindset of defeat, for he knows that this surely will bring it down upon his head. David, a boy of 16, did not retreat from the enemy. He hit the enemy with a force of the army of God behind him, and this is our mandate as well.
1 Samuel 17:50 So David prevailed over the Philistine with a sling and a stone, and struck the Philistine and killed him.
