Eleanor Roosevelt said "Courage is doing what you didn't think you could.".
Courage is more than facing or conquering fear, it is believing in ourselves: that we can do what is needed, that we can stand for justice, that we are able to change the world. It is believing in those things despite it seeming otherwise, or as Margaret Mead is attributed as saying "Never doubt that a small group of thoughtful, committed citizens can change the world: indeed, it’s the only thing that ever has."
Or more succinctly, in the word of Ted Lasso "Believe."
Someone from the crowd answered him, ‘Teacher, I brought you my son; he has a spirit that makes him unable to speak; and whenever it seizes him, it dashes him down; and he foams and grinds his teeth and becomes rigid; and I asked your disciples to cast it out, but they could not do so.’ He answered them, ‘You faithless generation, how much longer must I be among you? How much longer must I put up with you? Bring him to me.’ And they brought the boy to him. When the spirit saw him, immediately it threw the boy into convulsions, and he fell on the ground and rolled about, foaming at the mouth. Jesus asked the father, ‘How long has this been happening to him?’ And he said, ‘From childhood. It has often cast him into the fire and into the water, to destroy him; but if you are able to do anything, have pity on us and help us.’ Jesus said to him, ‘If you are able!—All things can be done for the one who believes.’ Immediately the father of the child cried out, ‘I believe; help my unbelief!’
