2 Corinthians 10:3 – For though we live in the world, we do not wage war as the world does. The weapons we fight with are not weapons of the world. (NIV 1978)
My Musings – It is a sad fact that we often cannot tell the Christians apart from the lions based upon their actions.
My Advice – In your fight to “get ahead” make sure it is a noble and honorable fight. It you have to fight for things the way the world does, perhaps the battle is not worth it. You either need to change your tactics or find another battlefield.
