"Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked". (Eph 6:16)
Someone made a comment on this that really resonated with me. Paraphrasing, they said that fiery darts were much more dangerous than regular darts/arrows. A dart might be able to penetrate a chink in some armour, but it would only do localised damage, whereas a fiery dart once it has penetrated will consume the rest of the body, and quickly.
You can definitely see the correlation here to temptation and sin - that it is never localised, that it does affect 'all' of us, once acted upon. I think that the reverse is also true though that good attributes can consume the bad too. I hope that we will increase our faith, thereby increasing our protection from these nasty fiery darts, that just keep on coming!
