According to Paul in Colossians, which of the following is not a sign of newness of life in Christ

According to Paul in Colossians, setting minds on things that are earthly is not a sign of newness of life in Christ. Paul encourages believers to seek the things that are above, put to death what is earthly, put off the old nature, and forbear one another. The focus on earthly things is seen as a hindrance to the new life in Christ, as believers are called to focus on spiritual things and grow in their relationship with God. Therefore, putting one's mind on things that are earthly is seen as a sign that one is still living in the old way of life, rather than experiencing the newness of life in Christ.
