Press on...press on...press on...

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. 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, I press on toward the goal for the prize of the heavenly call of God in Christ Jesus. 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. Only let us hold fast to what we have attained. 

(Phil. 3:12-16, NRSV)
