Philippians 3:15-18

All of us who are mature [pursuing spiritual perfection] should have this attitude. And if in any respect you have a different attitude, that too God will make clear to you. Only let us stay true to what we have already attained. Brothers and sisters, together follow my example and observe those who live by the pattern we gave you. For there are many, of whom I have often told you, and now tell you even with tears, who live as enemies of the cross of Christ [rejecting and opposing His way of salvation]
