The answer God gave Jeremiah is “Don’t.” Don’t pray for them because He isn’t going to listen! For those who would argue that God hears every prayer, Adonai tells Jeremiah why He won’t listen and His words are for this exact day and time.
Jeremiah’s warning was not heeded by the men and women of Israel. They didn’t care that they worshiped other gods contrary to what God commanded. Instead they remained rebellious in their stony hearts and fervently declared they weren’t going to change their wicked ways. They believed that their prosperity came from the Queen of Heaven and not from the God of Israel so they continued their abominations until judgment came.
The New Testament does not use the word trinity nor did Yeshua or the Apostles teach this concept of God. Though the followers of Messiah saw the power of God through the risen Savior, recognized the voice of God in the flesh as Yeshua, they did not teach three different parts or entities to God.
