Our job in life is to fulfill our mission here so that we can live with Hashem for all eternity. If a person had been praying and doing extra mitzvot, that is exactly the way a Jew is supposed to respond when things are difficult for him. Every day that a person achieves being an eved Hashem is a successful day. Hashem knows our mission here much better than we do. And if He keeps a certain situation the same way for an extended period of time, it’s only because He knows we need to experience it to succeed in our mission here. The best thing we can do is to continue serving Hashem to the best of our ability in those circumstances that He wants us to be in. If our only goal in taking on extra mitzvot is to get out of the problem we are experiencing, then we will feel like we are failing in our efforts. But if our goal is to do our jobs in the world properly then we will feel accomplished with every day that passes, knowing we are doing what we are supposed to. If we could manage to serve Hashem with happiness even though we have not been receiving what we wanted, it makes the avodah infinitely greater.
Hashem is always looking out for our best interests. If we’ll stay the course and continue serving Him properly, we will then accomplish what we are meant to accomplish here.
