The ESV translates the verse like this:1
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.
For I know the thoughts that I think toward you, saith the LORD, thoughts of peace, and not of evil, to give you an expected end.
For 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.
In Jer. 29:11, God is saying that his plans for his people are good plans — God’s people may face difficulties in life, but God plans on blessing them with peace and safety.
