The centurion's faith is commendable because he had received the Word of God. In asking Christ to heal his servant by His word, he shows that he trusted God's Word. He believes that all that is necessary is for God's Word to be spoken for healing to occur in even the most desperate case. The centurion's faith is great because it did not require the bodily presence of Christ to heal, surpassing even that of the nobleman whose son was healed (John 4:49). His faith is also shown to be greater than that of Mary and Martha, who also thought Christ had to be present to heal their brother Lazarus (John 11:21, 32).
