There are two aspects to the Lord. He is watchful over those who follow him, for them he is a sanctuary from the perils of the world. However, to those who ignore his warnings he is an obstacle in their path. His will cannot be denied and will be followed to salvation or denied to damnation. In the case of Judah, their denial of the warning of the Lord will become a snare in which Jerusalem will be caught by the invading army of Assyria.
