Jeremias 1

Jeremias 1:5

This, too, seems unworthy to pass over in silence in praise of John. Although he was not yet born, yet already he prophesies and, while still in the enclosure of his mother's womb, confesses the coming of Christ with movements of joy since he could not do so with his voice.… In this regard I think that the prophetic phrase is appropriate that says, "Before I formed you in the womb I knew you, and before you were born I consecrated you." We ought not to marvel that after he was put in prison by Herod, from his confinement he continued to announce Christ to his disciples, when even confined in the womb he preached the same Lord by his movements. — SERMON 5:4
