Does it say anywhere in the Bible to not pray for someone? Does God ever say not to pray for someone?
Surprisingly, God does tell one of his prophets not to pray for someone. That can be found in Jeremiah 7:16; 11:14; and 14:11. God tells Jeremiah not to pray for the nation of Judah because they have as many idols as there are villages. Because of their idolatry God has determined to send the nation into captivity in Babylon, and it appears that he tells Jeremiah not to pray for them because then he would have to grant Jeremiah’s request for clemency.
The nation had gotten so far away from God that his mercy and patience were exhausted. Fortunately, he never seems to have gotten to that point with individuals. Since these are the only passages where someone is told not to pray for someone else there is no instance in which we would not be able to pray for somebody. No person is so bad that God will not save them.
