I must work the works of him that sent me, while it is day: the night comes, when no man can work.
All Commentaries on John 9:4 Go To John 9
George Leo Haydock
AD 1849
Whilst it is day. That is, during all the time of this mortal life; the night comes, that is, death. (Witham)
He speaks of that night of which mention is made is St. Matthew chap. xxii. Cast him into exterior darkness. This is a night in which none can work, but only receive the reward of their labours. If you wish to work, work now whilst you live; for beyond the grave there is neither faith, nor labour, nor repentance. (St. Chrysostom, as above.)
