But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses us from all sin.
1 John 1:7 NET
Transparency is essential for fellowship.
But then, what about privacy? That is only for the details of one’s life, which do not have much bearing on the (other person’s) knowledge of oneself.
Integrity = truthfulness + privacy
Common faith ~ shared light
