And Jesus stood, and commanded him to be brought unto him: and when he was come near, he asked him, 41Saying, What wilt thou that I shall do unto thee? And he said, Lord, that I may receive my sight." (Luke 18: 40-41)
Jesus does not ignore us when we call out to Him.
In fact, He wants us to call on Him directly.
The blind beggar on the side of the road asked about all the people passing him by.
When the same beggar learned that Jesus of Nazareth was the one passing through, he cried out for his grace and mercy.
Just as He promised in the first parable mention in Chapter 18, Jesus responded to the beggar's need, even though He did not seem to right away.
As we call on Him, God wants us to see more of Him, to have a greater understanding of how compassionate, how gracious He is.
He does not heal from afar, but He heals us as we come closer to our knowledge of Him, as we grow in grace and knowledge of the Lord (2 Peter 3: 18).
Do not be discouraged if you pray to Him, and you find that you are not healed of whatever disease or saved from the problem you pray about. Believe that you are coming closer to Him, and that when You see more of Him, He will give you beyond what you ask or think.
