Our hope is in a Person, not in an event.
So though we might experience disappointment and setbacks, our hope is not defined by that, but by the word of God. Hope can be a quiet confidence, while we are waiting, while we take one step after another.
“I wait for the Lord, my whole being waits, and in his word I put my hope.”
Psalms 130:5 NIV
