The Gospel story is about Jesus curing the paralytic at the pool of Bethesda. It is the third of the "signs" which assure us that Jesus is the Son of God, and that we have life through him. It is a story that reminds us that our lives will be healthy to the extent that we center them on Jesus.
The First Reading present us with Ezekiel's vision of fresh water flowing from the temple down to the Dead Sea and beyond. For us the the temple is the church where we attend Mass, the water flowing from the temple us would be the life of Grace that we distribute to those with whom we make prayerful contacts through our days.
