The centurion is the first Gentile that we see in the Gospel of Matthew after the wise men. Like the wise men, the centurion recognizes that Jesus is Lord.
Even though his servant's illness is severe (paralysis), the centurion strongly believes that Jesus has the power to heal him. The centurion does request to see the healing take place. He does ask for proof. The Roman, instead, trusts humbly and firmly that Jesus will do something good for his servant in need.
Jesus sees this as faith. Faith is the assurance of things hoped for, the conviction of things not seen (Hb. 11:1). It is confidence about something that we cannot control.
In many stories, the healing itself seems central to the episode. Today, however, Jesus puts the focus not on the healing, but rather, on the deep faith of this Roman
Am I in need of healing in some way? Is there a physical pain that is causing me to suffer? Is there an invisible struggle that prevents peace from dwelling in my heart?
Can I humbly ask Jesus to help me? Do I firmly believe that he will bless me with something good?
Lord, though I am not worthy of Your love, I trust in You. Have compassion on me, Your servant.
