Hashem's Greatest Joy Is to Give
The Ohev Yisroel teaches that Hashem's true delight in creation lies in making room for others to receive from Him.
Explaining the verse in which Hashem calls the dry land Earth, the Ohev Yisroel begins with an everyday observation. What we do all the time gives us little pleasure. A person's real joy comes when he is able to give to someone else and they gain from him. So too with the Creator. Everything flowing from Him is boundless, and a limitless world could not really be received by anyone. His highest delight lies in having restrained His infinite light, so that creatures could take pleasure in it and receive His goodness. That is why, the Rebbe says, He named the dry land with a word that hints at desire, the land that Hashem wants, and why the Torah says He called it, an expression of affection. Creation itself, he teaches, is an act of love, and a world with room for receivers is the delight of the Giver.

If giving is Hashem's own joy, then leaving space for others is a way of walking in His ways. Today, choose one place to hold back so someone else can take: let a friend finish a story, hand a task to a child instead of doing it yourself, or let a colleague receive the credit. Also give with warmth, so that the receiver feels they are doing you a favor. Receiving gracefully, when it is your turn, is part of the same gift.
