I first came across Mark McMinn when I got hold of what is itself a really helpful book, Integrative Psychotherapy, co-authored with Clark Campbell. It sent me looking for author things Mark has written and Why Sin Matters is top of that list for me (but you ought to also see his more specialist work, Sin and Grace in Christian Counselling).
Why Sin Matters is neither soft on sin, nor light on grace. It affirms the terrible problem that sin is, in all the fulness of its putrid infection, and it then shows the absolute sufficiency of God's grace to overcome sin. He makes helpful use of Rembrandt's work, 'The Return of the Prodigal' and writes with a disarming honesty (itself the fruit of grace).
Every pastor - indeed, every Christian - would benefit hugely from reading this.
