This is a man who realises that the heart is deceitful above all things, and desperately wicked (Jeremiah 17:9). He is desperately aware that the garment of his redemption is not his own. It was graciously given to him by the sacrifice of his Saviour on the cross at Calvary. He knows that it is by the mercy of God that he is not consumed. He knows daily that he transgresses God’s commandment and is in need of daily repentance and cleansing and renewal.
