In Christian faith, sin is more than an opportunity to talk about grace and conversion, it is an opportunity to experience both. As always, there is the distinction between the spiritual and the psychological. The first leading to a deeper and more finely tune sense of trust, love, obedience,  relationship, the covenant relationship between our Maker and His creatures. The latter leading to clarity, understanding and peace of mind. I am not suggesting we seek sin, any more than I would suggest we seek suffering. However, considering sin, suffering and injury are commonplace occurrences in this ego driven world; I am suggesting we neither embrace or resist them, we stand firm and not be harmed by them. Just as wise persons seek out problems because they need their gifts, we experience and release our sinfulness, suffering and injury because we need the strength and courage gained by grace and conversion
