" Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will."
We are not to copy the behaviors and customs of the world, but to allow God to transform us into a new person by changing the way we think. Then we learn to know God's will for us which is good, pressing and pleasing.
I believe in you and you need to believe in yourself.
