When you get in your car, you expect it to start. When you flip a switch, you expect a response. When you drive to work, you expect it to be there. Expecting is knowing without seeing.
Faith is expecting without knowing. Faith is expecting beyond sight, reason and sometimes, hopes. Faith is expecting the mountain to move. Faith is knowing without seeing…the substance of things hoped for, the evidence not seen.
