Romans 12:2

And you people must not be conformed to [the values and standards of] this age, but you should become transformed [i.e., changed in attitude and action] by having your mind renewed [i.e., to think in a totally different way]. Then you will be able to determine [and practice] God's will, the thing that is good, and acceptable and perfect.

1 Peter 2:5

And you yourselves are also like living stones, being constructed into a spiritual house. For you are like holy priests who offer spiritual sacrifices that are acceptable to God through Jesus Christ.
