Know you not that they who run in a race all run, but one receives the prize? So run, that you may obtain.
All Commentaries on 1 Corinthians 9:24 Go To 1 Corinthians 9
Augustine of Hippo
AD 430
It is not from the one who wills nor from the one that runs but from God who has mercy that we obtain what we hope for and reach what we desire. Esau was unwilling and did not run. Had he been willing and had he run, he would have obtained the help of God who by calling him would have given him the power both to will and to run.
