25 So he, leaning back on the chest of Jesus, said to Him: “Lord, who is it?”
John took the prompt of Simon Peter and asked the question that all the disciples wanted to ask (perhaps with the exception of Judas).
Perhaps we have been in situations where we are in a group and the group all have the same question in mind. It may be a class of students where their tutor has said something, but what they have said leaves their pupils uncertain as to what the tutor meant. The class may look to someone to be bold enough to question the tutor for clarification.
This is what John was seeking to do.
There will be times for us all when we may need to go to Jesus on behalf of someone else and ask Him for guidance for them. There will be times when we look to the Holy Spirit for a word of knowledge, not only for ourselves, but also for others as well. It is in those times when we acknowledge our lack of knowledge and understanding and we must remember the wise words of Solomon:
 Trust in the LORD with all your heart; do not depend on your own understanding.  Seek His will in all you do, and He will direct your paths – Proverbs 3.5-6 (NLT).
One of the amazing privileges of all followers of Jesus is that of being able to have access to Him. We do not have to queue up; we do not have to put in a written application and hope that Jesus will read it. Just as John had an ease of access to Jesus, so do we.
It is Jesus who told us:
“Keep on asking, and you will receive what you ask for. Keep on seeking, and you will find. Keep on knocking, and the door will be opened to you” – Matthew 7.7 (NLT).
It is far better for us to make our requests known to Him than to remain silent and sink deeper into ignorance.
