For though we walk in the flesh, we do not war after the flesh: II Corinthians 10:3
It is quite easy to think after salvation that only our enemy has changed, not our methods of battle. In the same way that we lived for Satan, we now fight against him and against the world, our flesh, and the flesh of others. The Holy Spirit in these inspired words is clearly teaching us otherwise though, and we would be wise to consider what He is saying.
In the larger context, Paul is defending his authority and making sure that the Corinthians understand that his words of condemnation are more than just the rantings of an over-sensitive apostle. To help make his point, he uses two different connotations of the word flesh in verse three, first referring to the physical body, and then referring to the old nature of man and the resulting ways of the world. In a sense he is saying “sure I walk around in a weak, physical body, but my body is not my strength. My weapons are spiritual weapons, mighty through God.”
As Christians and spiritual leaders, we have to understand that God has a new set of weapons, or I could use the word methods, for us to use. We don’t take the world’s ideas and adapt them to Christianity, we take the Bible and use its methods, realizing by faith that God can work in ways that do not make sense to us. Why does servant leadership work? It doesn’t on Wall Street or Main Street, but God takes our obedience and does a miracle in our followers. There is no natural reason for it to work because natural refers to our old nature, not our new one, but yet it works in the church. Or take giving, where we have more by giving more away. The method is illogical, but to God it makes perfect sense. And may I also mention influence? The world has its way of influencing people and making friends, but God’s ways are totally different.
The point is this – don’t follow the world just to get a result that you want, follow Christ to get the result that He wants. There is amazing power in God’s methods of battle.
