There is no doubt that Jesus called his first disciples, and he calls us, to conversion. Yet the sacrament of conversion - the sacrament of penance - has fallen on hard times over decades. There is a much diminished use of the sacrament, and frequent reports of dissatisfaction with the experience of it on the part of both penitents and confessors. Reversing this trend would seem to require a changed mentality. The author of this book aims to equip us for just such a change.
