Jeremiah 29:11 - 14A
11For I know the plans I have for you," says the LORD. "They
are plans for good and not for disaster, to give you a future and a hope.
12In those days when you pray, I will listen. 13If you look for me in earnest,
you will find me when you seek me. 14I will be found by you," says the
LORD...
