12 Not as though I had already attained to it, either were already perfect: but I follow, if I may apprehend that for whose sake also I am apprehended of Christ Jesus.
13 Brothers, I do not count myself that I have attained to it, but one thing I do: I forget that which is behind, and endeavour myself to that which is before,
14 And follow hard toward the mark, for the prize of the high calling of God in Christ Jesus.
Philippians 3:12-14, THE HOLY BIBLE
