In today's Gospel reading from Matthew 9, a woman suffering hemorrhages for twelve years came up behind Jesus and touched the tassel on his cloak. She said to herself, "If only I can touch his cloak, I shall be cured." Jesus turned around and saw her, and said, "Courage daughter! Your faith has saved you." And from that hour the woman was cured.
I am still trying to understand faith more. If I cut my finger, it would be nice that I pray to the Lord for healing and it's healed instantly. In reality, it doesn't happen like that. First of all, I know that the finger will heal in a few days and the pain I feel is not bad at all, and I really don't want to bother the Lord for that. In other words, my strong desire to be healed is absent. Should I be suffering as much as the woman with hemorrhages, I probably would strongly desire that the Lord heal me and he very likely will do just that. So faith comes forth from our heart's desire in a natural way. I'd like to mention again the time my son could have died from a virus attack. While he was in critical condition in ICU, I walked up to him and said without hesitation "Be healed in the name of the Father and the Son and the Holy Spirit," while making the sign of the cross on his forehead. Three days later, he recovered and was sent home. So I think the secret is to trust in the Lord with all your heart and pray when you are called to pray. You cannot force yourself nor the Lord.
