Philippians 3:12-16 New International Version - UK (NIVUK)
12 Not that I have already obtained all this, or have already arrived at my goal, but I press on to take hold of that for which Christ Jesus took hold of me. 13 Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: forgetting what is behind and straining towards what is ahead, 14 I press on towards the goal to win the prize for which God has called me heavenwards in Christ Jesus.
Following Paul’s example
15 All of us, then, who are mature should take such a view of things. And if on some point you think differently, that too God will make clear to you. 16 Only let us live up to what we have already attained.
