Jeremiah 29:10-13 NIV
This is what the LORD says: “When seventy years are completed for Babylon, I will come to you and fulfill my good promise to bring you back to this place. For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future. Then you will call on me and come and pray to me, and I will listen to you. You will seek me and find me when you seek me with all your heart.
