Luke 1:38 - Coke's Commentary on the Holy Bible

Behold the handmaid, &c.— Mary expressed in this answer both great faith and great resignation. She believed what the angel had told her concerning her conception, and wished for it, not regarding the inconveniences to which she might be exposed thereby; as well knowing that the power of God could easily protect her. It is worthy of our remark, that Mary, though a young virgin, should so readily believe an event, in itself so much more wonderful than that which Zacharias, thoughan aged priest, had found it so difficult to credit; and it may be observed, that the sacred writers are particularly careful to record instances of this kind, in which God does as it were out of the mouths of babes and sucklings perfect his praise.
