Excerpt from an exposition by Alexander MacLaren, quoted in the Bible Hub
1“The sin of Judah is written with an iron stylus, engraved with a diamond point on the tablets of their hearts …”
“Sin committed is indelibly written on the heart of the doer.
‘The heart,’ of course, in Hebrew means more than merely the supposed seat of the affections. It is figuratively the centre of the spiritual life, just as physically it is the centre of the natural. Thoughts and affections, purposes and desires are all included, and out of it are ‘the issues of life,’ the whole outgoings of the being. It is the fountain and source of all the activity of the man, the central unity from which all comes. Taken in this wide sense it is really the whole inner self that is meant, or, as is said in one place, ‘the hidden man of the heart.’ And so the thought in this vigorous metaphor may be otherwise put, that all sin makes indelible marks on the whole inward nature of the man who does it.
Now to begin with, think for a moment of that truth that everything which we do reacts on us the doers.
We seldom think of this. Deeds are done, and we fancy that when done, they are done with. They pass, as far as outward seeming goes, and their distinguishable consequences in the outward world, in the vast majority of cases, soon apparently pass. All seems evanescent and irrecoverable as last year’s snows, or the water that flowed over the cataract a century ago. But there is nothing more certain than that all which we do leaves indelible traces on ourselves. The mightiest effect of a man’s actions is on his own inward life. The recoil of the gun is more powerful than the blow from its shot. Our actions strike inwards and there produce their most important effects. The river runs ceaselessly and its waters pass away, but they bring down soil, which is deposited and makes firm land, or perhaps they carry down grains of gold.
This is the true solemnity of life, that in all which we do we are carrying on a double process, influencing others indeed, but influencing ourselves far more.“
Prayer: Lord, help me to a better understanding of the human heart, and how to be transformed in my heart
