Mary believed that God chose her to give birth to the Son, but others surely would doubt. Under Mosaic Law, if Joseph posed as a child’s father, God would punish the Israelite nation.

Jesus put religious leaders on the spot by asking whether baptism by John had heavenly or human origin. Even when they saw repentant sinners change their ways, those self-righteous leaders refused to change their minds about believing and heeding John the Baptist. When something seems too good to be true, how do we choose what to believe?
