They say unto him, Lord, that our eyes may be opened.

Matthew Henry's Concise Commentary

20:29-34 It is good for those under the same trial, or infirmity of body or mind, to join in prayer to God for relief, that they may quicken and encourage one another. There is mercy enough in Christ for all that ask. They were earnest in prayer. They cried out as men in earnest. Cold desires beg denials. They were humble in prayer, casting themselves upon, and referring themselves cheerfully to, the Mediator's mercy. They showed faith in prayer, by the title they gave to Christ. Surely it was by the Holy Ghost that they called Jesus, Lord. They persevered in prayer. When they were in pursuit of such mercy, it was no time for timidity or hesitation: they cried earnestly. Christ encouraged them. The wants and burdens of the body we are soon sensible of, and can readily relate. Oh that we did as feelingly complain of our spiritual maladies, especially our spiritual blindness! Many are spiritually blind, yet say they see. Jesus cured these blind men; and when they had received sight, they followed him. None follow Christ blindly. He first by his grace opens men's eyes, and so draws their hearts after him. These miracles are our call to Jesus; may we hear it, and make it our daily prayer to grow in grace and in the knowledge of the Lord and Saviour Jesus Christ.
