God is light. If we fellowship with Him, we will have His light. Therefore, the fellowship of life brings us into the light of God so that we may have His light. Being in darkness is proof that we do not have fellowship with God or that our fellowship has been broken. If we have fellowship with God or with His children, we certainly are in the light of God. The fellowship of life and the light of God cannot be separated. If we are in the fellowship of life, we are in the light of God. If we are not in the light of God, we have lost the fellowship of life.
