The power of God is light and the power of Satan is darkness. This is the way in which the servant of God must discern things. Since God is light (1 John 1:5), it is God alone who defines what light is, just as Satan shows us what the opposite of light is – darkness.
This truth provides in God’s Word the deeper understanding for the spiritually antithetical relationship that exists between God’s light, which represents holiness and goodness and awakening and clarity, and Satan’s darkness, which connotes fear and despair and wickedness and blindness. In this ensuing struggle, darkness eclipses the light, while the light in turn dispels the darkness.
In this teaching Jon Touchstone explains how God makes the distinction between light and darkness. Showing how Jesus became the light of the world, and those that follow after him shall not walk in darkness, but shall have the light of life.
