Who among the following was consecrated and appointed a prophet before he was born?
The prophet who was consecrated and appointed before he was born was Jeremiah. Before he was even conceived, God had already set him apart to be a prophet to the nations. This is recorded in Jeremiah 1:5, where God says to Jeremiah, "Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations." This shows that God has a plan for each person's life, and that He can call and equip them for a specific purpose from before they were even born. Therefore, Jeremiah's calling as a prophet was not something he achieved through his own efforts, but rather a divine appointment that he was entrusted with from the beginning of his life.
