Into the Light
Never think that because our sins were forgiven that they are covered; they are not. Covering of sin was an Old Covenant dispensation until the time of reformation (Heb. 9:10). Rather sin is now out in the open because "light is come into the world" (John 3:19), and we must come to the light - “for that which makes manifest is light”.
Fellowship with the Father and with His Son is a moment by moment walking "in the light as He is in the light", whereby we are washed in the blood of the Lamb from all sin and unrighteousness. Such is a state of utter reliance and dependence on the ”once and for all” sacrifice of Jesus Christ. If for one moment we step out of the light, we walk out of fellowship and into the darkness of sin, where there is neither cleansing nor covering.
