The same applies to serving God. You should only think of today, the present hour. When a person wants to begin serving God it seems like a heavy burden which he will never be able to bear. But if you think that you have only today, it will not be a burden at all. Man's world consists of nothing except the day and the hour that he stands in now.
Tomorrow is a completely different world.
Every mitzvah which a person does in this world, creates a lamp with which he can explore the treasure house of the King after his passing. There are two kinds of fear of Heaven. There are people who fear God because of His greatness and exaltedness as the Ruler and Master of the Universe. This level of fear adds completeness to God's Name. Such things can evoke the awareness of God within a person, and this second level of fear is the source of the influx of blessing into the world.
