Is God's 'ink' the kind that you can eraze?

Jer. 17: 1 – The sin of Judah is written with a pen of iron, and with the point of a diamond; it is engraved upon the tablet of their heart, and upon the horns of your altars.

The deceitful heart Jer. 17: 9 The heart is deceitful above all things, and desperately wicked; who can know it. I, the Lord, search the heart; I test the conscience, even to give every man according to his ways, and according to the fruit of his doings.

Job 19: 24 – That they were engraved, with an iron pen and lead, in the rock forever. (on a rock for permanence, because papyrus or skin would perish in time).

When God writes beauty in your heart, does it last? Smiles… just wondering!
