Imagine for a moment visiting the doctor because of a recurring pain in your knee. After filling out the necessary paperwork and entering the examination room, you will likely undergo a diagnostic process that extends far beyond that specific joint.
A nurse might take your temperature, test your reflexes, and check your blood pressure—actions that seemingly have nothing to do with your knee. It may feel counterintuitive to evaluate your entire body when you already know where the discomfort is located. However, while you are certainly aware of the pain you feel, you may not yet understand its true origin.
The reality is that your physical discomfort is often just a symptom—a presenting issue rather than the root cause. A comprehensive examination is necessary not to confirm that your knee hurts, but to determine if a deeper, more substantial problem is triggering that pain. This same diagnostic rigor is essential when addressing emotional or spiritual distress, providing a vital lens through which to view the prophetic invitation from Isaiah: “Come, all you who are thirsty, come to the waters.”
Sure, you know what you’re feeling, but what you’re feeling might only be the symptom. It might be what is a presenting issue – not the true source of the pain. That’s why the full examination is necessary. It’s not to determine whether or not your knee hurts, but to determine what is the root cause of that singular pain. It’s to make sure there isn’t something deeper and more substantial causing the pain you’re experiencing.
And perhaps the same kind of diagnostic process is not only valid but necessary when it comes to other moments of pain and distress. Maybe that’s another lens through which to view these words from the prophet Isaiah:
“Come, all you who are thirsty,
come to the waters;
and you who have no money,
come, buy and eat!
Come, buy wine and milk
without money and without cost.
Why spend money on what is not bread,
and your labor on what does not satisfy?
Listen, listen to me, and eat what is good,
and you will delight in the richest of fare.
Give ear and come to me;
listen, that you may live.
I will make an everlasting covenant with you,
my faithful love promised to David” (Isaiah 55:1-3).
There is need here. There is desire here. There is even pain here. We are thirsty, hungry, and unsatisfied. But according to the prophet, we might well look to temporary alleviation of that thirst, hunger, and dissatisfaction instead of going through the full diagnostic process.
But if we did go through the process we might well discover that there is indeed a deeper kind of illness below the surface.
To be more relevant, think about it like this: These last months have been lonely for many of us. We have acutely felt the desire of close, physical relationships as many of those have been stripped from us. And so we are feeling lonely. Now we might think that the solution for that loneliness is to just get around people again. And perhaps it is – at least in part. But we do ourselves a great disservice if we do not think a little bit deeper. If we don’t at least ask the question of whether this feeling we have might be something else presenting as loneliness.
So we look to the heart level – the soul level – to try and diagnose our true thirst. Our true hunger. Our true desire.
And at the bottom of it all, we find that there is indeed a longing there that can only be filled by a vibrant relationship with God and His Son, Jesus Christ. It is from that deep well of satisfaction that everything else flows.
For the prophet, the one who had been in the very throne room of God, this is a question of simple logic. If you have drunk from the well of living water, if you have feasted on the bread of life, if you have bathed in the riches of grace, then it simply makes no sense to try and quench that thirst or hunger or desire with anything else. But that logic is, of course, dependent on whether or not we have the courage and the faith to actually trace our desire to the root. To diagnose the true source of the thirst we are feeling.
But let’s not be people like that. Let’s not be that impatient and short-sighted. Let’s be the ones who diagnose ourselves and look deeper. Let’s be, as the prophet says, a listening people who are willing to not just settle for presenting symptoms.
For there is water. There is bread. There is wine and milk. There are riches. And they all come by grace.
