 Light n.
 1. That agent, force, or action in nature by the operation of which upon the organs of sight, objects are rendered visible or luminous.
 Note: ☞ Light was regarded formerly as consisting of material particles, or corpuscules, sent off in all directions from luminous bodies, and traversing space, in right lines, with the known velocity of about 186,300 miles per second; but it is now generally understood to consist, not in any actual transmission of particles or substance, but in the propagation of vibrations or undulations in a subtile, elastic medium, or ether, assumed to pervade all space, and to be thus set in vibratory motion by the action of luminous bodies, as the atmosphere is by sonorous bodies. This view of the nature of light is known as the undulatory or wave theory; the other, advocated by Newton (but long since abandoned), as the corpuscular, emission, or Newtonian theory. A more recent theory makes light to consist in electrical oscillations, and is known as the electro-magnetic theory of light.

    the offspring of the divine command (Gen. 1:3). "All the more

    habitually described among the Hebrews under imagery derived

    Light came also naturally to typify true religion and the
    felicity it imparts (Ps. 119:105; Isa. 8:20; Matt. 4:16, etc.),
    and the glorious inheritance of the redeemed (Col. 1:12; Rev.

    6:16). It frequently signifies instruction (Matt. 5:16; John

    of righteousness" (Mal. 4:2; Luke 2:32; John 1:7-9). God is

    (2 Cor. 11:14), and of John the Baptist, who was a "burning and
    a shining light" (John 5:35), and of all true disciples, who are
    styled "the light of the world" (Matt. 5:14).
