In our Gospel passage, Jesus is attending a meal at which some Pharisees and other righteous people were present. There is a hypothesis that the man with the open wound was intentionally brought into the dinner to trap Jesus to see if He would perform a healing on the Sabbath. Usually, a sick person would never have been invited as a guest. But Jesus was quite happy to take the bait.
Immediately, He healed the man and then sent him on his way.
Even today, there are many instances when people appear particularly religious and pious yet fail to show respect for and care for others in times of need.
Our LORD's approach is always to treat others with love and respect regardless of the circumstances. He calls us to follow His example. Jesus' way of relating to others must be our way as well. All religious and pious practices are nothing if we do not have love, mercy, and compassion and act upon these qualities to help those in need.
