Why evangelism is always non-negotiable

A diocesan bishop told me recently about a congregation that had decided that it was not “called” to evangelism at that particular time, but would reconsider it in five years. “Why do they think it’s an option?” he asked. “If they had decided they weren’t called to worship, they would have expected me to turn up on the door the next day insisting that, because they were a Christian church, this wasn’t an option for them. Why do we not grasp that evangelism is a non-negotiable?”
