Philippians 3:12-16

Not that I have already obtained it [this goal of being Christlike] or have already been made perfect, but I actively press on so that I may take hold of that [perfection] for which Christ Jesus took hold of me and made me His own. [1 Cor 9:24; 1 Tim 6:12] 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.
