Richard J. Foster said this quote

Confession is a difficult Discipline for us because we all too often view the believing community as a fellowship of saints before we see it as a fellowship of sinners. We feel that everyone else has advanced so far into holiness that we are isolated and alone in our sin. We cannot bear to reveal our failures and shortcomings to others. We imagine that we are the only ones who have not stepped onto the high road to heaven. Therefore, we hide ourselves from one another and live in veiled lies and hypocrisy.But if we know that the people of God are first a fellowship of sinners, we are freed to hear the unconditional call of God's love and to confess our needs openly before our brothers and sisters. We know we are not alone in our sin. The fear and pride that cling to us like barnacles cling to others also. We are sinners together. In acts of mutual confession we release the power that heals. Our humanity is no longer denied, but transformed.
