John 13:9

Verse 9. Not my feet only, &c. Peter, with characteristic readiness and ardour, saw now that everything depended on this. His whole salvation, the entire question of his attachment to his Master, was involved. If to refuse to have his feet washed was to be regarded as evidence that he had no part with Jesus, he was not only willing, but desirous that it should be done; not only anxious that his feet should be cleansed, but his hands and his head--that is, that he should be cleansed entirely, thoroughly. Perhaps he saw the spiritual meaning of the Saviour, and expressed his ardent wish that his whole soul might be made pure by the work of Christ.
