Take heed to yourself. 

Everyone who competes for the prize is temperate in all things. Now they do it to obtain a perishable crown, but we for an imperishable crown. Therefore I run thus: not with uncertainty. Thus I fight: not as one who beats the air. But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified. § Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against the principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.Those who are Christ’s have crucified the flesh with its passions and desires. If we live in the Spirit, let us also walk in the Spirit. § For as many as are led by the Spirit of God, these are sons of God. § Meditate on these things; give yourself entirely to them, that your progress may be evident to all.
