John 16.28-30 cont.
28 I came from the Father and have come into the world; again I leave the world and I am going to the Father.”
29 His disciples said: “See, now You speak plainly, no longer speaking figuratively.
30 Now we know that You know all things and that You have no need that anyone should question You. By this we believe that You came from God.”
When we are young there is a tendency for us all to think that we ‘know it all’, although our experience is very much the opposite. Yet many of us speak about things as though we are an authority of them. As we grow older we begin to realize how little we really do know, although we have gained a lot of understanding through the experiences we have encountered on our journey through life.
Through what Jesus said the disciples had come to the conclusion that Jesus did know all things. This is an important revelation, and one that we all need to come through.
There is absolutely nothing that Jesus does not know. Since He and the Father are One, then He has exactly the same knowledge and understanding as the Father.
There is nothing not known to the Father and Jesus, the Son.
Therefore, Jesus knows all about us, He knows the deep things in our life. He knows what we think even before it begins to be formulated in our minds. He knows the state of our souls; He knows the temptations that we face, and the ones that we are most vulnerable to.
King David wrote these words:
 O LORD, You have examined my heart and know everything about me.
 You know when I sit down or stand up. You know my every thought when far away.
 You chart the path ahead of me and tell me where to stop and rest.
Every moment you know where I am. – Psalm 139.1-3 (NLTL.
The disciples told Jesus that He had no need that anyone should question Him. The reason for this is that Jesus was speaking plainly. He was speaking with clarity. People would understand what He said; therefore, there was no need for them to ask the meaning of what He had said.
We can be thankful that everything Jesus says to us is easily understandable. We may or may not like what He says, but His message is as clear as crystal.
We must make sure that we do not cloud the message of His gospel.
