Following Jesus takes more than words, it requires everything in us.

I beseech you therefore, brethren, by the mercies of God, that you present your bodies as a living sacrifice, holy, acceptable to God, which is your reasonable service. 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.                 Romans 12:1-2
