Worship, in the Reformed understanding, is a dialogue between God and his people, a dialogue in which God speaks, and we respond.

Should Christians call out sin? Firstly, we have to be very careful before we do. We need to make sure we've checked in with ourselves, our own sin, our motivation, and our desired outcome.
The reason we are so fearful of our sin, the reason we are so hesitant to acknowledge it, is because we are so used to it. We’ve become so accustomed to living a life of sinful patterns that, even though we may pay lip service to wanting to be holy, the fear of letting go of our sinful nature is overwhelming.
