How can we sit in our church pew, comfortable that our ticket has been punched, and that somebody else will take care of that lost soul?

Ezekiel 33:6 

But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman’s hand.
