And behold, a leper came and worshiped Him, saying, “Lord, if You are willing, You can make me clean.” Then Jesus put out His hand and touched him, saying, “I am willing; be cleansed.” Immediately his leprosy was cleansed. (Matthew 8:2-3 NKJV)

Notice the approach of the leper. First, he came to Jesus, second, he worshiped, third, he asked for the Lord’s will, then finally, he expressed his faith that the Lord was completely able to heal and make him clean. We can learn much from the order and attitude of the leper’s “prayer.”
Then notice Christ’s response. First, he touched the leper. Don’t miss this. He could’ve just healed him from a distance like He did the centurion’s servant. Leprosy was a devastating disease. It made one unclean, so that they were excluded from Temple worship. Lepers were excommunicated from the community. They were required to yell, “Unclean!” as they approached to warn others away. The disease was progressive and caused sores and white scales to appear, damaging the skin, nerves and eventually muscle tissue. Extremities (nose, ears, fingers, toes, etc.) would die and rot away over time. No one would touch them for fear of catching the disease. Yet, Christ touched the leper, expressed His willingness to heal him, then with a word, said, “Be cleansed.” And he was.
Christ was willing not only to heal us from a distance, but to come to us, touching us, and taking our sin upon Himself and thus cleansing us from all unrighteousness. Christ is willing and able to save those who come to Him.
