Why would a powerful God allow his people to suffer loss?

Westminster Confession of Faith Chapter 3 Article 2

The sermon explores the theological complexities surrounding God's sovereignty and human free will, specifically addressing the idea that God does not ordain events because He foresaw them. It refutes the notion that God is merely responding to future events, instead emphasizing His proactive and purposeful choice, exemplified in the biblical narrative of predestination. The message underscores that God's choices are not contingent on human decisions but are rooted in His own will and character, highlighting the importance of fearing God and trusting in His wisdom, even amidst suffering and loss, as demonstrated in the historical account of Israel's defeat and the tragic events surrounding Eli and his sons.
