vs 12 and 13 if properly understood and internalized, would give us a proper outlook of God and how we make our demands to Him.
I've seen people pray and they seem like they are begging God or trying to convince Him to intervene in their issues.
Vs 12 said
While Jesus was in one of the towns, a man came along who was covered with leprosy. When he saw Jesus, he fell with his face to the ground and begged him, “Lord, if you are willing, you can make me clean.”
He said if Jesus is willing to help him, check out Jesus reply in vs 13..
Jesus reached out his hand and touched the man. “I am willing,” he said. “Be clean!” And immediately the leprosy left him.
So you see, Jesus is always willing to help us and provide a solution to that issue of ours, so instead of talking to Him as a servant we should come as a heir and son as represented in Hebrews. 4:16 which says
Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
So this should our outlook in prayers, GOD IS WILLING AND ABLE.
God bless us all.
