When I define hope I usually put it in the context of my faith in God. I may say "I hope so" when something is stated to possibly happen. But the underlying theme is my belief and confidence in God's ability and His sovereignty to accomplish the things I am trusting Him for.
I am learning how to hang onto God more patiently while still maintaining my expectations. God does have a time and a season for everything under the sun. That includes the things I hope for. I may not receive them in the way or form I expected, but my hopes are often realized when I get to the heart of the matter.
God knows my heart and the longings I have - to be known by Him; to be loved by Him; to be accepted by Him. Those are the needs that God addresses and meets. I may long for others to love and accept me, but I can be disappointed at times. That is when I can turn to God and find those needs met.
My greatest longing is to one day see Jesus; to be in God's presence and worship Him forever. That is my constant hope in this life which carries me through when my temporal hopes are not realized.
