Mark 14:38
Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak — watch and pray is the Gethsemane application of the Olivet watch command. The flesh is weak is not an excuse but a diagnosis: the disciples' failure to pray in advance is why they will fail under pressure. The spirit is willing acknowledges the genuine desire; the flesh is weak explains why the desire is insufficient without prayer.
