What does this reveal about Jesus?
Jesus responds in sympathy to urgent pleas which are given with faith in his ability.
Notes & Applications:
At first it appears that Jesus asked a seemingly ignorant question "What do you want me to do for you?" It seems to me it would have been intuitively obvious what the blind man wanted. But I think the point is to give this man an opportunity to ask in faith specifically what he wanted.
At times our prayers are too vague, when then particular need we have is obvious. By faith we should be specific, asking about that particular thing. For then when our prayer is answered glory goes to God more explicitly. Notice how this ended. He followed Jesus - praising God, and the people praised God.
This man needed sight to literally follow Jesus better. What do you want that will help you to follow Jesus better? Don't be afraid to ask the Lord, nor be hindered by others who may discourage you from doing so.
