I think the default for many Christians today is to turn to "professional" counselors. I think that there is certainly a role for this. Being able to sit down with someone who has a great deal of experience discussing trauma can be a huge help.
But there must be a role for believers in the church counseling one another. After all, isn't the goal that we, as a church body, know the Word of God well enough and know one another well enough that we can carefully apply the truth of Scripture to each other's lives in such a way that true comfort and healing are found?
Our default should not be to seek counsel outside the congregation, but inside. That's why I appreciated David Powlison's blog post yesterday, "The Local Church is THE place for Biblical Counseling."
