Luke 17:14

Shew yourselves. As required by the law of Moses (see on Mark 1:44).

As they went. Healing was conditional upon an act of faith. They were not healed so long as they lingered in Jesus’ presence, but only as they proceeded to carry out His instructions. When they left Jesus they were still leprous. It is evident that had they awaited visible evidence of healing before setting out for Jerusalem, where they were to be pronounced “clean,” healing would never have come. It was necessary for them to act in faith, as if they were already healed, before healing actually came. He who does not come to the Lord in faith need not expect to “receive any thing of the Lord” (James 1:7; cf. Heb. 11:6). Without obedience there is no faith, for “faith without works is dead” (see James 2:17-20). He who has genuine faith will act in accordance with every requirement of God, but without faith obedience is impossible and unavailing. Neither can exist alone without the other (see James 2:17).
