Philippians 3:13-16

Brothers and sisters, I do not consider that I have made it my own yet; but one thing I do: forgetting what lies behind and reaching forward to what lies ahead, I press on toward the goal to win the [heavenly] prize of the upward call of God in Christ Jesus. 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.
