Even more difficult than a one time death is living each day denying oneself...
Tit 2:12 teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and gdly in the present age,
Rom 12:1 I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.
Rom 12:2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
Bringing every thought into captivity...
2Co 10:3 For though we walk in the flesh, we do not war according to the flesh.
2Co 10:4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds,
2Co 10:5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ,
2Co 10:6 and being ready to punish all disobedience when your obedience is fulfilled.
