Endure to the end as you contend for the faith

Phil. 3:12 Not that I have already obtained this or am already perfect, but I press on to make it my own because Christ Jesus has made me his own. 13 Brothers, I do not consider that I have made it my own. But 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 upward call of God in Christ Jesus. 15 Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you. 16 Only let us hold true to what we have attained.

What an overcomer would say.

Philippians 3:12-16 (KJV)

12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.

13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,

14 I press toward the mark for the prize of the high calling of God in Christ Jesus.

15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
