Do not be anxious
Sinclair Ferguson in The Sermon on the Mount: Kingdom Life in a Fallen World:
It is only when we take our lives out of the Father's hands and have them under our own control that we find ourselves gripped with anxiety. The secret of freedom for anxiety is freedom from ourselves and abandonment of our own plans. But that spirit only emerges when our minds are filled with the knowledge that our Father can be trusted implicitly to supply everything we need.
