There is an old word that describes going to war and killing sin. Mortify it. When you see that word, it means, kill zone. DEFCON 1. Going nuclear. Annihilation. Is this the posture of your heart toward your sin?
For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.” (Romans 8:13 ESV)
The key phrase here is, “put to death the deeds of the body.” The Greek word for put to death is used 11 times in the New Testament, 9 for actually killing people. One example is Stephen, the first martyr, who was put to death. Same word. This is not a nice word. This is a bloody word. A word of execution. It simply means, kill it. Legalism says, stop it. Romans says, kill it. This requires a posture toward sin that is much more like an assassin. Ruthless. Cold, hard hatred of sin.
Jesus said the same when he said, “if your right hand causes you to sin, cut it off.” (Matthew 5:30) It is not physical dismemberment, but a spiritual dismemberment that sees sin as leading to death. It is an abuse of grace that makes us OK with sin thinking, I’m going to heaven anyway. That is an incredibly dangerous posture toward sin and calls into question if we truly understand Jesus shedding his blood for that sin.
