What does John 9:11 mean?
This particular miracle provides us with many valuable lessons. One, first hinted at here, is the simplicity of our testimony. The man speaking was born blind (John 9:1–2), but was miraculously granted sight by Jesus (John 9:6–7). When pressed about what happened to so drastically change his life, the man has a simple answer: Jesus put mud on my eyes and said to wash, so I did, and now I can see. This man will be interrogated by the Pharisees, and yet he will consistently give the same answer. In fact, when pressed to give a deeper explanation, he will respond with a classic statement: "One thing I do know, that though I was blind, now I see" (John 9:25).God does not expect us to have deep, advanced knowledge in order to be saved. Nor do we need to have extensive experience or a well-polished story in order to reach others for the sake of Christ. In most cases, our most potent tool is to give a simple explanation of what God has done for us (Mark 5:19). Not only is this personal and real, but it's undeniable: we know what we have experienced!
Another helpful perspective here is to consider what would have happened had the man refused Jesus' command. In this particular case, Jesus didn't instantly heal, He gave the man a task to perform. This is not an uncommon tactic by God, even when it comes to healing (2 Kings 5:1–14). Putting muddy clay on the man's eyes certainly gave him an incentive to wash, and God often uses "pressure" in our lives to encourage us in certain directions. But this man's blessing was effectively on hold until he acted in obedience. Not all of God's work in our lives is this way, and we certainly can't presume that God "owes" us when we do certain things. However, we should also recognize that God does not expect us to be passive (John 9:4; Matthew 5:16), and sometimes His commands are for our own benefit.
