Jeremiah 20:9 — I say to myself, I will not mention Him, I will speak in His name no more. But then it becomes like fire burning in my heart, imprisoned in my bones; I grow weary holding it in, I cannot endure it.
If this is the case for a mere prophet, what must it have been like for the Immaculate Conception who so clearly saw our ignorance and sin. But then she burst forth in praise of the Most High in the Magnificat (Luke 1:46-50):
My soul proclaims the greatness of the Lord; my spirit rejoices in God my savior. For he has looked upon his handmaid’s lowliness; behold, from now on will all ages call me blessed. The Mighty One has done great things for me, and holy is his name. His mercy is from age to age to those who fear him.
