The desire to draw close to God and understand His ways is an ongoing, intensifying spiritual journey. It requires a shared, immense effort to attain true knowledge of Him [רד״ק, מצודת ציון]. This pursuit is far more than a simple intellectual exercise; it is the underlying secret of all wisdom and the very reason humanity was created. To reach this spiritual peak, a person must first acquire broad knowledge across various disciplines, using them as a ladder to climb higher [אבן עזרא]. This knowledge is an essential first step, as a person can truly serve God only after learning to know Him [רד״ק]. However, this journey contains a built-in paradox. Because it is impossible for a human mind to fully grasp God, the ultimate peak of knowledge is the humble realization that one cannot know everything. Therefore, the more a person learns, the more they understand that they must continue their pursuit of this divine truth [מלבי״ם].
This spiritual progress is compared to the natural, gradual appearance of the sunrise. The morning light is clear and guaranteed to appear [מצודת ציון, ביאור שטיינזלץ]. Just as a person who sees the first faint rays of dawn is absolutely certain that the sun will soon rise, anyone who genuinely pursues knowledge of God can be completely confident that they will find Him [מצודת דוד, רש״י]. This understanding does not happen all at once. At first, a person can only grasp God indirectly by observing His actions in the world. Then, much like the morning light that slowly grows stronger and brighter, human understanding expands moment by moment until the full truth is finally revealed [אבן עזרא, מלבי״ם, רד״ק].
In response to this human effort, a promise of divine blessing is given, arriving as naturally and certainly as the forces of nature. God's response is compared to the late rain that saturates the earth and waters the growing crops [מצודת ציון, רש״י, ביאור שטיינזלץ]. There is a clear law of cause and effect at play. Just as physical rain falls only after mist first rises from the ground, the spiritual rains of enlightenment and salvation flow down from heaven only after human action and awakening occur below. Even if this divine abundance does not arrive immediately, it is guaranteed to appear at the end of days, just as the late rain always comes in its proper season [מלבי״ם]. When this response comes, it brings life, immense goodness, and a deep healing that no human being could ever provide [רש״י, מצודת דוד, אבן עזרא]. Just as rain revives the dry earth and forces dead seeds to sprout, this divine salvation brings profound renewal. For a person trapped in deep sadness who feels as though their spirit has died, this sudden rush of divine grace will feel exactly like coming back to life [רד״ק].
