Philippians 3:14
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 — the repetition of 'I do not consider myself to have attained' emphasizes humility. 'Forgetting what lies behind' (ta opisō) suggests relinquishing past achievements (and perhaps past failures: both pride and shame are obstacles). 'Straining forward' (epekteinomai, stretching oneself) is intense forward movement. The singular focus ('one thing I do') establishes Christ as sole goal.
