Its easy to critique and admonish those “over there” [other people / churches / denominations] when they are doing something wrong or something we don’t agree with. Problems closer to home though are always much harder to speak to, much more likely to earn harsh criticism from one’s friends, and therefore much more likely to be ignored.
What happens when we don’t police ourselves? What happens when we don’t hold ourselves to the same standards we expect of others?
We as the church, the bride of Christ, represent Him wrongly before the world. We become hypocrites; “do as I say not as I do” type of an organization.
Corporate integrity bound up in personal holiness is what we should be striving for. It starts with us, personally! If we are more Christ like – the church will be more Christ like. Isn’t that our God given call? This is the will of God, your sanctification [1 Thess. 4:3].
I suspect if we would adhere to the idea of personal holiness, maturity, growing in Christ-like-ness, sanctification; the policing would take care of itself and so would the hypocrisy.
