I moved this to another section because I think that you might be able to gain much in way of insight when you analyze the meaning of the saying in light of Tolstoy's work.  On the most basic of levels, the statement affirms both the presence of a divine power and the idea that judgment and deliberation are intrinsic to that force.  The saying stresses the idea that a higher power is able to fully grasp and understand what defines "truth" and that judgment is going to be aligned to this.  Many times, individuals believe that the power of God in seeing and acting is almost instantaneous.  Yet, the quote, and what Tolstoy argues in his short story of the same name, is the idea that humans might not fully grasp the plan of the divine, but there is a plan and to doubt it might be to doubt the fiber of the divine.  In Tolstoy's story, a man is wrongly imprisoned.  The man becomes more religious while in prison, and through this experience, he obtains a greater sense of moral transcendence.  The "truth" of spiritual elevation is something that Tolstoy believed God saw and delivered in the form of truth that waits.  In this, one sees the power of the saying in that one must be able to understand that God's sight and immediate gratification based off it are human constructs and might not be readily understood by mortality.  The plan of the divine is present and the quote argues that it will be revealed in due time.
