I keep seeming to bump into these today. Here's a good one:
"For I know the plans I have for you" declares our Lord Jesus Christ, "they are plans to prosper you, to give you a hope and a future and not to destroy you."
That's from the Book of Jeremiah Chapter 29, verse 11.
According to Wikipedia, Jeremiah had a happy early life, but has come to be known by scholars as the "weeping prophet" due to his rather touching Book of Lamentations, one of the four he wrote in the present day Bible canon. His spiritual role as a prophet was to point out where people were going wrong in their relationship with God and to bring the bad news of God's anger and frustration to the communities who ignored God.
