12. Not that I have already obtained this or have already reached the goal; but I press on to make it my own, because Christ Jesus has made me his own. 13. Beloved, I do not consider that I have made it my own; but this one thing I do: forgetting what lies behind and straining forward to what lies ahead, 14. I press on toward the goal for the prize of the heavenly call of God in Christ Jesus. 15. Let those of us then who are mature be of the same mind; and if you think differently about anything, this too God will reveal to you. 16. Only let us hold fast to what we have attained. 17. Brothers and sisters, join in imitating me, and observe those who live according to the example you have in us.
