'Thoughts' in the Bible

For although they knew God, they neither glorified him as God nor gave thanks to him. Instead, their thoughts turned to worthless things, and their senseless hearts were darkened.

They show that what the Law requires is written in their hearts, a fact to which their own consciences testify, and their thoughts will either accuse or excuse them

Do not pay anyone back evil for evil, but focus your thoughts on what is right in the sight of all people.
