Jeremiah 29:11 (NIV)

11. 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.

Jeremiah 20:11

But the Lord is with me like a mighty warrior;
    so my persecutors will stumble and not prevail.
They will fail and be thoroughly disgraced;
    their dishonor will never be forgotten.

(NIV version)
