This morning I had an echocardiogram. Don’t know what that is? Neither did I until this morning. It’s basically an ultrasound of the heart. This is one of a number of health checks I’ve had in recent months. Since it’s six years since I was diagnosed with cancer, and two years since I’ve had chemo, and since we’re planning on moving cities, we thought it wise to book in for a major service or two. So far, I’ve had the cameras in both ends and seen some of the damage chemo has left behind. I’ve managed to take on another ‘C’ disease—well developed coeliac. So we’ve had a pantry purge and I’ve started to become one of those difficult people who is always asking what’s in the food I’ve been given. I’ve had lung function tests and discovered that despite the beating my lungs have taken I’m sitting on the low end of average for a bloke my age. My bone density has been checked and I’m osteopaenic. Don’t know that word either? Well, it’s much better than osteoporosis and osteopathetic. I’ve even spoken to my first specialist, a lung physician, who was willing to explore another ‘C’ word—cure. I liked the sound of that one, but we can’t ever know for sure.
Back to the echocardiogram. They were checking the health of my heart. Occasional atrial fibrillation or arrhythmia. I’ve had it a few times over the years and I’ve usually been able to explain it away. But then the heart is one organ to take seriously. It was behaving itself today, but there was something a little remarkable. The echo showed that my heart has become somewhat hardened. The muscle has thickened. Probable causes are high blood pressure and insufficient exercise. Yes, I know what to do. More exercise, get the heart working a bit more. And slow down, relax, rest, recreate, de-stress. In other words, I mustn’t harden my heart any more than it is.
As I walked away from the cardiologist this morning, I remembered having heard something like this before:
12 See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. 13 But encourage one another daily, as long as it is called ‘Today’, so that none of you may be hardened by sin’s deceitfulness. 14 We have come to share in Christ, if indeed we hold our original conviction firmly to the very end. 15 As has just been said:
‘Today, if you hear his voice,
do not harden your hearts
as you did in the rebellion.’
Hebrews 3:12-15 NIV
I need to pay attention to my heart. This muscle is indispensable to my continued welfare and existence. I can’t do without it.
But, more importantly, I must also pay attention to my spiritual ‘heart’—the centre of my being, my values, my conscience, my choices, my priorities. God is calling me to listen to his voice. Not some mystical connection found in solitary introspection, but his message of good news focusing on Jesus. The good news is that Jesus is the only one to live for, the one who deserves everything, including my complete allegiance. He has given his life for me, to rescue me from the futility and judgment that comes from living for myself.
When God reminds me of this fact, I mustn’t harden my heart against him. When my will aches for independence, when I simply want to do my own thing, when I’m tempted to despair, when I’m feeling that God is remote or irrelevant, then I mustn’t harden my heart. When the world around me is shouting that there is no God, and when consumerism keeps luring me to live myself, then I must listen to the true word of God. The voice that reminds me that my heart will never be satisfied until it finds its rest in God.
And I urge you too to listen to God. Take a look at your spiritual echocardiogram, get your spiritual heart checked, while you still can. Good heart health is smart and spiritual heart health matters even more.
