"Do you want to be well?" Jesus was not one for small talk. He point-blank asks the man if he really wants to be healed. This means a dramatic change of lifestyle for this man. I wonder if he stops to consider the consequences and responsibilities of his answer.
One more thing: Jesus is the living water that heals us. But with that comes a responsibility to "not sin any more". Do you have a holy water font in your home? If so, is it filled? If not, get one and encourage your children to bless themselves daily as a reminder of Jesus' healing love for them.
Prayer: Dear Lord, You are the living water that cleanses, heals and renews me. Be with me and help me to sin no more. St. Agapitus, pray for me. Amen.
