Faith is a Telescope

I found the following passage in Muscular Christianity by P. G. Mathew encouraging, so I wanted to share it with you:

Faith provides a firm ground to stand on while we await the fulfillment of God's promises.  By faith we can be sure that all of God's promises to us will be fulfilled.  Faith is assurance in the present.  It gives the object hoped for a present power in the soul as if it were already possessed.  Faith gives us a vision of things future.  It is like a telescope that enables us to see distant objects and be energized by that sight to live our lives in the present. Paul says, "We live by faith, not by sight" (2 Cor. 5:7).  By faith we see spiritual realities now and deal with the present in the light of that reality.
