there is really much to be said on the kiruv topic…
i just want to add in 2 points:
1.I believe it was the Chofetz Chaim (correct me please if i’m wrong) who said that just as one needs to set aside a 10th of a persons money for maaser, for tzedakah, so too a person has an obligation to set aside a 10th of there time to kiruv.
2. having said that, kiruv is not necessarily and only going out to the wilderness or wherever and being mekarev. for those Yidden who don’t agree with such an approach, kiruv can be also SMILING AT THE CASHIER!
Kiruv- to bring closer- there are many ways to bring His children closer. Invite them for a meal. Or if you don’t want to be so out there, try this, we did it, send it anonymous [or not… ;)], a small menorah with candles and the Brachah for Chanukah, something cute for Pesach… all these are ways to bring closer…
Any other ideas?
