Jeremiah--Crying

I was reading in Jeremiah one morning this week chapter 30 precisely and read this beautiful promise from God to His children: "But I will restore you to health and heal your wounds" (v. 17). I know that there are different takes on who God was talking to in the Old Covenant with some saying those promises are for the Children of Israel. Others say that, "Every promise in the Book is mine, every chapter, every verse, every line." I find myself vascillating between these two opinions; however, I want to take this promise that He will restore me to health and heal my wounds as my mantra. He will restore me to health and He will heal my wounds. With that belief I get through the day--without crying.
