Be Still and Know Your Mighty Fortress.
This Psalm is a reminder of the power, sovereignty, protection, and deliverance of the Lord. The presence of the Lord in Jerusalem and the presence of the Lord with New Testament believers reminds us that we cannot be moved because God fights for us. Whether natural disaster (v. 2-3) or human enemy (v. 4-10) our job is to wait and trust in the power of our God. (v. 10)
