However, this does not answer the important question: Are the tenses real? Is the “Now” real? Most writers in Christian philosophy defend the view that “my Now,” “my present choice,” or “my present awareness” actually represents something real. This will lead most writers in Christian philosophy to the A-theory. They normally find it obvious that the concept of time has to be related to the human mind. Therefore it becomes more natural to describe time by means of tenses (past, present, and future) than by means of instants (dates, clock-time, etc.). With tenses, one can express that the past is forever lost and the future is not yet here. Without these ideas one cannot hope to grasp the idea of the passing of time.

Phenomena such as memory, experience, observation, anticipation, and hope are all essential for the way time is understood. Notions of past and future time, the interpretation of the past, and expectations of the future are all interwoven in the human mind. Nevertheless, A-theorists claim that the distinction between past and future is objective, or at least intersubjective.
