[Dr. Eckleburg]

In all of these passages of scripture you cite, the people that Paul, Jesus and His brother James are talking or writing to are believers and the message is the same, "become and live out what you are already".

AMEN! That's beautiful. "Become and live what you are already" in order to "prove" the will of God true.

"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God." -- Romans 12:2

[annalex]

but be ye transformed by the renewing of your mind

This calls to be what you are not, the exact opposite of what you claim as you say "Become and live what you are already" in order to "prove" the will of God true".
