Walking along a street in Tel Aviv an observant Jew decided to try his luck at bringing a secular resident of the bustling metropolis closer to his Jewish roots. He courteously stopped a passerby and offered to study some Torah with him for five minutes.
To his pleasant surprise the fellow responded that he was interested in the offer and even invited him into his nearby home. Together they learned some Chumash, and when the five minutes were up our hero got up to leave.
"Wait", said his host. "If we already studied together I would like you to give your blessing to me and my wife who have been married many years and have not yet been blessed with children."
"Who am I to give you a blessing which will bring you the fulfillment of your wish!" was the humble response. "But what I can do is give you a suggestion that will help. Invite some of your neighbors and friends to participate in a weekly Torah shiur in your home and I will supply the teachers. In the merit of such an initiative you will be blessed."
The offer was accepted, the shiur became a regular event for many years and the hosting couple was soon blessed with their first child.
