Spiritual serenity, the psalmist admits, ought to be cultivated in spite of the shaking mountains and agitated waters.
This spiritual calm, that God commands, does not come from a lack of troubles. It derives from a steady, deep reflection on the ways God has intervened in history on behalf of his people (cf. Romans 15:4).
So as your world crumbles around you, the call from Scripture is: don’t flinch in faith in God. Stand still—not because of a self-made confidence, not because you are the most composed person in the face of disaster, not because “you’ve seen it all.”
Be still because of what you know about God.
It is “God’s past” that provides calm for “our future.” Know that he is God! Know it, not merely intellectually, but practically, spiritually, and emotionally. He is your God. He is the ruler of kingdoms of this earth and the all-powerful Creator of the Universe.
If you are the last man or woman standing, be still.
“God is our refuge and strength, a very present help in trouble. Therefore we will not fear, though the earth do change” (Psalm 46:1-2a).
