James Macdonald said this quote
“ Our view of human problems determines who is qualified to speak to them. If sin is the primary human problem, then those with the theological and practical expertise in dealing with sin – in its varied and complex forms – should lead the way in the field of people-helping. Unless we have an accurate and robust conception of sin, the church will concede much of its work to outside professional and will be ill-equipped to cooperate with them when needed. ”
