Everything isn't good. The expectation that everything is or should be good is why there is a lot of pain, hurt, anxiety, depression, separation, and frustration in society. Life is messy and difficult and frankly it sucks sometimes. Hoping that things will always be good is, what one of my mentors would say is "a hopeless hope". The HOPE is that "God causes things to work together for the good". So even when things are messy and difficult and ... we have the hope that God will take it all and make it purposeful and meaningful and complete.
"God isn't trying to make our lives easier; He wants to make them more meaningful." Bob Goff
