John 9:8-12: in context

The man born blind, now healed, becomes the talk of his neighbors. Some say, isn't this the beggar who used to sit here? Others say it only looks like him. He settles it: I am the man. They press him: how were your eyes opened? And he tells them plainly what happened: a man called Jesus made mud, put it on my eyes, told me to wash in the pool of Siloam, and I went and washed, and I received sight. But when they ask where Jesus is, he simply says, I do not know.

The healed man's testimony is striking for its simplicity and its honesty about its limits. He cannot answer every question; asked where Jesus is, he says plainly, I do not know. He is not a theologian; he cannot explain who Jesus is, or how the healing worked, or where his healer has gone. But there is one thing he can say, and he says it clearly: a man called Jesus did this, and I who was blind now see. Later, pressed further, he will put it even more simply: one thing I know, that though I was blind, now I see. He testifies not to a theology he has mastered but to a thing that happened to him, an experience he can report even without understanding it fully. There is encouragement here for our own witness. We may feel unqualified to testify to Christ because we cannot answer every question, cannot argue the theology, cannot explain all the difficulties; and so we stay silent, thinking we must have all the answers to speak. The healed man had no such answers; asked where Jesus was, he said, I do not know. But he could tell plainly what Jesus had done for him, and that simple testimony carried weight. We can always do this: tell honestly what Christ has done in our own lives, what we have experienced of him, even when we cannot answer every question about him. I was blind, and now I see is a testimony no argument can refute, because it is not an argument but a report of what happened. We do not need to be able to explain everything to bear witness; we need only tell, honestly and simply, what we have seen and known of Christ ourselves. That which we have seen and heard, John writes, we declare to you. The healed man could not say where Jesus was, but he could say what Jesus had done for him; and that simple, honest testimony to our own experience of Christ is a witness available to every one of us, whatever we cannot explain.

Do I stay silent about Christ because I feel I must have all the answers, unable to argue the theology or explain every difficulty, or can I learn from the healed man, who could not say where Jesus was but could tell plainly what Jesus had done for him, that I can always bear the simple, honest testimony of what I have seen and known of Christ in my own life?
