Sunday begins the season of Advent (the 4 weeks prior to Christmas Day). As we celebrate the incarnation of the Son of God, the Light of the world, advent becomes a ‘season of light’ in many ways.

The great American theologian B. B. Warfield wrote the following about the biblical concept of light…

Throughout the Scriptures “light” is used as the designation of all that is of consummate and unapproachable perfection, whether in the physical, intellectual, moral or spiritual spheres. In contrast with the darkness of sorrow and peril we have the light of joy and safety; in contrast with the darkness of death we have the light of life; in contrast with the darkness of error we have the light of truth; in contrast with darkness of sin we have the light of holiness; in contrast with the darkness of destruction we have the light of salvation. Physically, intellectually, ethically, spiritually, savingly, “light” is all that is pure and true, bright and holy and blissful. And light is the heritage of the saints. It is the sphere in which God lives, for we are to walk in the light as He is “in the light.”
