The “be still” part of that verse can be misinterpreted.
The actual language connotation is more closely akin to “cease striving [on your own]”. It’s more of an admonition to not rely on your own strength, wisdom, and efforts, but to turn to God.
I think that is how I generally understand “being still” to mean in this context...but the “be still doesn’t occur by itself...it says to “Be still and KNOW that I am God” which means to come to a place of rest and knowing that God is bigger than all of our circumstances and to take comfort in that fact....or as the 23rd Psalm says” He leadeth me beside the still waters, he restoreth my soul!”
