This is true every day of every life and I'm uncertain why we seemed surprised by this. We are tempted to think "If only this was different, I'd be happy. If only that fear would go away I'd have more energy to do positive things." In truth some of the most contented people I know are ones who have no expectation of having it easy or having things go their way. They have found their way past wasting energy on what they think is fair or what needs to happen. They don't waste time dwelling on what they have no authority over such as other people's behaviors or attitudes.
They have come to accept that we really know so little, have so little real authority except over how we will handle things ourselves. For some of us that comes through a belief that, though I don't know what is needed now and for the future, God does know, does care and does help us achieve our own best life if we are open to God's leading and blessings.
I can affirm with confidence and hope: GOD HAS GOT THIS....this being everything.
Deuteronomy 2: 3b-4 Don’t be discouraged! Don’t be afraid! Don’t panic! Don’t shake in fear on account of them, because the Lord your God is going with you to fight your enemies for you and to save you.”
