Dispositional sins are fully as injurious to the Christian cause as the more overt acts of wickedness.
Let us list a few of them: sensitiveness, irritability, churlishness, faultfinding, peevishness, temper, resentfulness, cruelty, uncharitable attitudes; and of course there are many more.
Many persons who had been secretly longing to find Christ have been turned away and embittered by manifestations of ugly dispositional flaws in the lives of the very persons who were trying to win them.
Unsaintly saints are the tragedy of Christianity.
