When those in power tell us to have faith what they usually mean is have blind faith. In reality blind faith is a subset of faith and one should be very judicious about where you use it. When one has faith they will have reasonable cause to believe the party they have faith in can come through. Even people in the Bible had reasonable cause to believe in Jesus’ miracles as his reputation had already been established. Upon having faith, one should see glimmers of the “not yet” showing up in the here and now. For example if your boss promises you a raise, observing him paying someone else a fair wage would point to this.
Of course those in power, Christian and secular, want to keep you thinking of faith as blind faith. They do this because blind faith is a tool for social control.
