But now you must also put away all the following: anger, wrath, malice, slander, and filthy language from your mouth. Do not lie to one another, since you have put off the old man with his practices and have put on the new man, who is being renewed in knowledge according to the image of his Creator.
(Colossians 3:8-10 Holman Christian Standard Bible®©)
If you are driving well and have to listen to someone in the back seat instructing you to speed up, slow down, change lanes, turn here, et cetera, it can be annoying. If you are living in surrender to the Spirit of Jesus, it will be costly to your flesh. However much of your flesh (the old man) is still around will be making lots of noise when you obey the King.
Requiring your flesh to be silent about how much something costs or about serving someone who has abused you or anything else that requires death to your flesh will prevent you from derailing in your obedience. Allowing that old man to continue to make noise in the back seat can distract you. The Holy Spirit fruit (Galatians 5:22-23) will give you power to throw the old man out of the car.
So I discover this principle: when I want to do good, evil is with me. For in my inner self I joyfully agree with God’s law. But I see a different law in the parts of my body, waging war against the law of my mind and taking me prisoner to the law of sin in the parts of my body. What a wretched man I am! Who will rescue me from this body of death? I thank God through Jesus Christ our Lord! So then, with my mind I myself am a slave to the law of God, but with my flesh, to the law of sin.
