Verse explainer
Paul isn't prescribing a life-hack about positivity — he's describing the posture of a man who knows he hasn't arrived yet and is straining with his whole body toward what's still ahead.
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,
BSBBrothers, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead,
The plain meaning
The verse sits inside Paul's frank confession that he hasn't yet grasped what Christ grasped him for (v. 12). He's using the image of a runner bent forward in a race — not glancing back at past victories or past failures, but every muscle straining toward the finish line. "Forgetting" doesn't mean emotional amnesia or denying what happened; it means not letting the past — whether proud credentials (vv. 4–6) or previous failures — anchor you where you are. The full sentence runs into v. 14: he's pressing "toward the mark for the prize of the high calling of God in Christ Jesus." The movement is toward Christ and the resurrection (v. 11), not toward self-improvement or a clean mental slate. Paul's point is single-minded forward momentum in a race he knows he hasn't won yet.
The common misreading
What the commentators say
Clarke insists that 'this one thing I do' marks the race as the sole business of Paul's life — not one priority among many. He reads 'reaching forth' (Greek epekteinomenos) as a picture of total physical exertion: every muscle and nerve engaged, the runner spending every particle of strength. Clarke stresses the urgency behind this: time is flying, eternity is near, and everything is at stake.
JFB warns that looking back reliably ends in going back — citing Lot's wife as the type. They read 'reaching forth' as a bodily image: hand and foot extended, body bent forward, the eye drawing the hand and the hand drawing the foot. The Christian's constant awareness of the gap between what he is and what he desires to be is precisely what keeps him moving rather than stalling.
Gill anchors the 'mark' in v. 14 as Christ himself — the center of all God's purposes, the substance of the covenant, the object toward which every grace and every duty points. He stresses that the prize is of God's grace and mercy, not of the runner's merit, and that it is Christ who holds it and will give it to all who finish — which makes the straining forward an act of faith, not self-achievement.
The word behind it
"Straining forward" or "stretching out toward." A vivid compound verb (epi + ek + teinō) conveying full-body extension — the posture of a runner lunging for the tape. Adam Clarke noted it pictures every muscle engaged. It appears only here in the New Testament, which underscores Paul's deliberate intensity. The word reframes the whole verse: this is not calm remembering and calm hoping, but urgent, strained, forward momentum.
