Advice from Paul

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.

For I say, through the grace given unto me, to every man that is among you,

not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. Romans 12:2,3
