If it’s difficult your on the right path
A kehilah in Europe a few hundred years ago was informed of two Jews that were taken hostage by a group of hooligans. If 10,000 rubles weren’t delivered to them within a day the two would be executed.
The Rabbi of the neighboring community nominated his Gabai to collect the entire sum. For Pidyon Shvuim is of the greatest mitzvot. The Gabai went from door to door. To his astonishment each household gave him a great sum. Moshe Cohen the shoe-maker gave him 50 rubles, when he thought he might manage to squeeze half a ruble from him. Within two hours the Gabai had collected the whole sum.
Ecstatically he approached the Rabbi with a large chest containing the 10,000 ruble. When the Rabbi heard how easily the money was raised he ordered that it be given back entirely. If Moshe Cohen gave 50, he’ll get back his fifty and so on.
Instead the Rabbi ordered that the toughest members of the community break in to the house where the two Jews were kept hostage. The men raided the house and discovered that the two Jews were actually Goyim in disguise. When the Rabbi was asked how he solved the mystery, he replied: “Whenever we approach a Mitzvah the Satan puts obstacles in our way. The greater the Mitzvah, the greater the obstacle. When I saw that people were so generous in giving for the great mitzvah of Pidyon Shvuyim, and that the Yetzer Harah did not try stopping it. I knew that this was not a Mitzvah, rather a scam!”
I heard this story from Rabbi Michael Laseri. I doubt that it’s a true story but it conveys a message.
Finishes of Rabbi Laseri: When you’re biking and it becomes difficult to peddle, that’s a sign your going up!
