"The missional church seeks to call both lost sinners to repent of their sin and religious people to repent of their religion for three reasons. First, both pursue righteousness apart from Jesus' grace, which is an offence to the gospel. Second, if only so-called sinners are called to repent, then these "sinners" wrongly think that the church is trying to make them into religious people, while the religious people fail to see that they are sinners too who need to repent and live humbly by grace. Third, it was the religious leaders whom Jesus most sharply rebuked and was most violently opposed by; if we are to follow the example of Jesus, we must be just as forthright with the religious while accepting that they will likely be our most vocal critics and opponents"
