Talk about non-instant gratification. The people God is speaking to here, are about to spend 70 years in captivity. Still I find it one of the most soothing passages in the Bible because it seems like something I could do. "You will seek me and find me, when you seek me with all your heart."

Jeremiah 29:11-13
For I know the plans I have for you, declares the Lord, plans for welfare and not for evil, to give you a future and a hope.
Then you will call upon me and come and pray to me, and I will hear you. 
You will seek me and find me, when you seek me with all your heart.
