What does the Bible say about God being all-sufficient?

In Genesis 17:1, God reveals Himself to Abraham as El Shaddai, which means 'God All-Sufficient'. This declaration emphasizes God's ability to fulfill His promises without reliance on human effort. The narrative underscores that only God's grace can produce the promised seed, contrasting it with the turmoil produced by human attempts to achieve God's purposes through fleshly means. Hence, God’s all-sufficiency is foundational for understanding our total dependence on Him for salvation and all aspects of life.
