John Trapp on Luke 22:15

Verse 15. With desire have I desired] How much more should we come with strong affections and lusty appetites to this holy Supper? It is a vertue here to be an holy glutton, and to drink hearty draughts; that we may go from the Table, as Christ from Jordan, full of the holy Ghost. For this end consider what is before thee, as Prov. 23. 1. not to restraine appetite, but to provoke it. And the rather because Christ thus earnestly thirsted after our salvation, though he knew it should cost him so dear. See Luke 12. 50.
