“What do you want Me to do for you? ” He asked them.” ‭‭Mark‬ ‭10:36‬ ‭HCSB‬‬

Does Jesus already know their request? He knows what is in their hearts but does He know what they are going to say? I have never read where Jesus answeres a question before it is asked. But He does always have a response to any question and it was usually with another question to make the person whom He is talking to stop and ponder. 

What must I do to inherit eternal life? — Why do you call me good? (Mark 10:11-12)

it is lawful to pay taxes? — Whose image and inscription is this? (Matthew 22:17-20)

By what authority are you doing these things? — Where was John’s baptism from? (Matthew 21:23-25)

doesn't your teacher pay the temple tax? — Who do the kings collect taxes from? (Matthew17:24-25)

Jesus wants to hear our questions! He wants to know our fears, doubts, concerns so that He may increase our faith, hope, and love. 

“The apostles said to the Lord, “Increase our faith.” “If you have faith the size of a mustard seed,” the Lord said, “you can say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it will obey you.”

“Now these three remain: faith, hope, and love. But the greatest of these is love.”

“Humble yourselves, therefore, under the mighty hand of God, so that He may exalt you at the proper time, casting all your care on Him, because He cares about you.”
