The answer is: Almighty God

Genesis 17:1 - The title "El Shaddai" signifies God's ultimate power and authority, often associated with His covenantal promises, particularly to Abraham. This name underscores God's capability to fulfill His promises, seen also in Genesis 28:3, where Jacob invokes it for blessing, highlighting its significance throughout the patriarchal narratives.

"El Shaddai" is a powerful and intimate title that not only emphasizes God's might but is also steeped in deep relational significance. This term, frequently translated as “Almighty God,” conveys something richer and more complex—they suggest a nurturing protector who provides sustenance and care. Some ancient interpretations relate “Shaddai” to a Hebrew root meaning "to nourish" or "to supply", which frames God as a source of essential support and sustenance for humanity.

In Genesis 17:1, this name appears when God establishes His covenant with Abraham, promising that he will be the father of nations. It signals that God possesses the ultimate authority to do more than simply fulfill a vow; He owns the sovereignty to manage the vast universe and every individual within it. There’s a sense of assurance in this title—it's not merely about power but also fidelity and devotion.

And this isn't just confined to Abraham or Jacob. In fact, the frequent invocation of El Shaddai—most prominently noticed in the blessings over subsequent generations—certainly emphasizes its transcending role in the fabric of Jewish history. It acts as a constant reminder that individuals, communities, and indeed the world can rely on divine presence and strength in times of need, evoking a timeless lesson of faith available to all. Thus, this title carries both weight of authority and the overwhelming promise of divine nurturing, echoing throughout the narratives into the hearts of many seekers today.
