Every person you have ever met, or ever will meet is desired by God to be drawn close with Him, and is deemed worthy of praying, praising, and loving Him. It matters not at all where they are from, what they look like, or what language they speak.
In our first reading we hear of how Naaman took the direction of Elisha and was healed of his leprosy. This was incredibly unusual for someone who was an Asyrian military commander, from a totally different culture, and system of beliefs. Yet his desperation for healing took him in a direction that led him to the one source of healing that could actually accomplish this. He even obtained not only the blessing of his King who worshipped other gods, and expected his followers to do the same, but also a letter from his king asking the king of Israel for his hospitality for this subject of his. This was remarkably bold since Naaman was effectively eclipsing the gods that he and his king worshipped, and opting to put his faith in the God of Israel. This was what was required for him to be cleansed. Naaman was willing to take a chance and make that defining leap of faith that God was looking for.
In our Gospel today we hear of others who were healed. Jesus cures ten lepers of their illness, that same illness that Naaman had been healed of by Elisha. Yet when they have been healed, only one has the gratitude to return and give thanks to Jesus for his healing. That one that returned was the most unlikely of the ten, because he too was a foreigner, a Samaritan. He was of a people that detested the Jews and had been in conflict with them for generations. Yet he knew what had taken place, and despite his differences, returned and gave thanks in a most profound way, he fell at Jesus feet, and glorified God. Jesus understood well the profound nature of the faith and humility this man displayed to come to Him for healing, and even more so to return to acknowledge this and thank Him in such a manner.
For each of us, the question is, how often do we have enough faith in our creator to truly lay our problems at His feet, and with complete confidence ask him for healing or resolution? What is more, how often when we receive graces from God, whether it be healing, spiritual insight, or help with our problems, do we then recognize and give thanks that God helped us? There is never a time that God does not care, and that he does not listen to us. If we ask something of Him in faith, he will hear us. If what we ask for is best for us, in that it aligns with His plan for salvation, we too can be confident of His help.
