We are a people consumed by the need to feel secure. We want to have a secure financial future. We want our children to be secure in school and their car seat and on their bicycles. We have color coded security levels at airports and train stations. We have metal detectors going up all over the place. For all our efforts at being safe and secure the reality is one can never be one hundred percent secure in a world infected with sin.
Yet this Psalm gives incredible hope for being secure. It does not say we will be free from turmoil. Quite the opposite. The earth still gives way. The mountains fall into the sea. The waters rage and roar like a tsunami. Kingdoms fall. Nations go to war. Bad things still happen. Our security is not in a world in which bad things never happen. Our security is in a God who is our fortress and no matter what happens to us, He is the Rock on which we stand. We also know that even should this world pass away, there is a city that will not be moved. There is a river that does not rage. The City of God is that place. It is His dwelling place and all who trust in Him have the security of a home there because He has promised it to be so.
God is our refuge and strength,
a very present[b] help in trouble.
2 Therefore we will not fear though the earth gives way,
though the mountains be moved into the heart of the sea,
3 though its waters roar and foam,
though the mountains tremble at its swelling. Selah
4 There is a river whose streams make glad the city of God,
the holy habitation of the Most High.
5 God is in the midst of her; she shall not be moved;
God will help her when morning dawns.
6 The nations rage, the kingdoms totter;
he utters his voice, the earth melts.
7 The Lord of hosts is with us;
the God of Jacob is our fortress.

Thank you for this thoughtful devotion based on the ever wonderful Psalm 46. So prescient given the pandemic and the fear that has been showered on the US population!
