Naaman the Syrian had a journey to travel before he was finally cured of his leprosy. God had already begun the process of helping him, through the little Israelite slave girl, but Naaman - being an important person - wanted to be treated as such and expected Elisha to come out and attend to him personally (Kings 5:10-14). It was only when his servants intervened that he consented to bathe in the river Jordan. Faith requires that we allow God to do things his way, not ours.
All the ten lepers had to do was to ask Jesus to heal them; and at his word they were cleansed. Nine rushed off to show themselves to the priests: perhaps they were so excited at what had happened, they could think of nothing but their certificate of health. Leprosy was a horrible, incurable disease and probably no-one had ever been lucky enough to be able to present themselves before. It was said that only the Messiah could cure it. The tenth leper, however, stopped to reflect on what Jesus had done for him. He was doubly an outcast, being not only a leper bur a Samaritan, despised by the Jews. He praised God and thanked Jesus.
When we recognise all that God continues to do for us, we open up a treasure house of faith, hope, love and wonder.
Now thank we all our God
with heart and hands and voices,
who wondrous things has done,
in whom this world rejoices.
