Chasidut do Jeremiasza 31:20

And now, if you have internalized our words up to here and want to hear further about the path that you will climb towards God and the means through which you will connect to Torah and divine service - then we can already hope that in the end, you will, God willing, reach the state in which it will be said about you, "You are a dear son to Me, a child that is dandled! For whenever I speak of him, I earnestly remember him still. I will surely have mercy on him" (see Jeremiah 31:19).

This is *the fire of love* of which it says (Song_of_Songs.8.7) "Many waters cannot quench the love." As we find (Sotah 21a), "A sin extinguishes a mitzvah, but does not extinguish Torah." (The Sages (Vayikra_Rabbah.2.3) similarly expounded the verse (Jeremiah.31.20) "A darling child to Me is Ephraim... whenever I just speak with him" -- "sufficient is My Speaking that I placed within him.") And it says (Jeremiah.23.29) "My words are like fire, declares the Lord."
