Watch your life and doctrine closely.
Everyone who competes in the games goes into strict training. They do it to get a crown that will not last; but we do it to get a crown that will last forever. Therefore I do not run like a man running aimlessly; I do not fight like a man beating the air. No, I beat my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize. – Put on the full armour of God so that you can take your stand against the devil’s schemes. For our struggle is not flesh and blood, but against the rulers, against the authorities, against the powers of this dark world against the spiritual forces of evil in the heavenly realms.
Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. – Because those who are led by the Spirit of God are sons of God. – Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress.
