Thinking, praying, reading, studying the Bible – when we do these things, we are reflecting on the Word of God. To reflect is to contemplate and/or consider, and God wants us to deeply reflect on His Word so that we can better understand Him.
“Can anyone break iron, The northern iron and the bronze?” – Jeremiah 15:12.
I know not, but probably the Bible here alludes to the superior excellence of a Damascus blade. I once happened to see this steel put to the test. It was in France, and in the chemistry class of the Sorbonne. In the course of a lecture on iron, Thenard, the professor, produced a Damascus blade, stating that he believed that these swords owed their remarkable temper to the iron of which they were made being smelted by the charcoal of a thorn-bush that grew in the desert. To put it to the trial, he placed the sword in the hand of a very powerful man, his assistant; desiring him to strike it with all his might against a bar of iron. With the arm of a giant the assistant sent the blade flashing around his head, and then down on the iron block, into which, when I expected to see it shivered like glass, it embedded itself, quivering but uninjured; giving, besides a remarkable proof of the trustworthiness of the sword, new force to the proverb, True as steel.
