“Being in the light that is the life of the New Covenant requires more than a profession of faith. Several times John contrasts what people say with what is actually the case (I John 1:6-7, 2:10). We do not have fellowship with Christ merely by saying we have fellowship with him. We must not only say we have fellowship with Light, we must actually walk in the light, especially by living in fellowship and love with our brothers in the church.” (Peter Liethart, From Behind the Veil, p. 52)
