There are at least three elements that make up a solid defender of the Christian faith.
You can’t fight if you don’t know how. You might be able to flail about, but you won’t be very effective. What’s worse is that you are just as likely to hurt yourself and those on your side than you are the enemy. Especially since part of the training process is developing the ability to tell the difference between friend and foe and properly take stock of a battlefield before charging off to engage the enemy.
Do your best to present yourself to God as one approved, a workman who does not need to be ashamed and who correctly handles the word of truth. -2 Timothy 2:15
The expression used of a 2nd lieutenant in the army is “butter bars”.
After completing OCS (Officer Candidate School), a large number of newly minted butter bars tend to think that they are General Patton reincarnated and have the belief that after months of schooling they know much more than 30 year combat hardened NCOs.
Like the army, we are prone to think that mere knowledge will be enough to face the enemy with, and unfortunately many (including myself) have rushed off into battle without spending the time to properly spar with our fellow brothers at arms first.
The reason for this is simple. We never want to go into battle without at least stress testing new tactics and ideas with our battle hardened comrades. Its better to find out that our armor and weapons aren’t up to snuff in the sparring ring where our opponent isn’t seeking to do permanent damage than it is to discover our shortcomings as the knife is plunged deep into our heart by a true enemy.
As iron sharpens iron, so one man sharpens another. -Proverbs 27:17
All the training and sparring in the world is pointless if it is not ultimately employed on the field of battle.
The primary means of advancing the kingdom of Christ is through winning the hearts and minds of those around us who have been captured by the enemies of false teaching and sensuous pleasure.
For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. -Ephesians 6:12
Because of this, it is incumbent on us to “be ready in season and out of season” (2 Timothy 4:2) to engage the enemy wherever we find him, in whatever form he happens to be in.
We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. -2 Corinthians 10:5
As we fight, it is important to keep in mind that the enemy is not “flesh and blood”. So when we are interacting with a non-Christian we should treat them with the utmost respect and civility. But that doesn’t mean we shouldn’t fight with every fiber of our being the thoughts and practices that have captured them.
The true soldier fights not because he hates what is in front of him, but because he loves what is behind him. -G. K. Chesterton
At the same time
Training, sparring, and fighting should be ongoing activities in each Christian’s life. Some might object that new Christians shouldn’t be rushed into battle for fear of their being cut down. To that I propose that we “go to the lions” and teach our new recruits how to fight by going with them into minor skirmishes. Part of the role of a mature Christian should be designating and delegating strategic targets of opportunity for less mature Christians.
However it is incumbent on all Christians to charge the gates of hell in order to advance the kingdom of Christ here on earth.
