It may be that Christians, notwithstanding corporate worship, common prayer, and all their fellowship in service, may still be left to their loneliness. The final break-through to fellowship does not occur, because, though they have fellowship with one another as believers and devout people, they do not have fellowship as the undevout, as sinners. The pious fellowship permits no one to be a sinner. So everybody must conceal his sin from himself and from the fellowship. We dare not be sinners. Many Christians are unthinkably horrified when a real sinner is suddenly discovered among the righteous. So we remain alone with our sin, living in lies and hypocrisy.
