How do we know God's providence in Joseph's life is true?

Genesis 45 reveals that Joseph recognized God's hand in his betrayal and subsequent hardships, stating, 'It was not you who sent me here, but God' (Genesis 45:8). This affirms the theological principle of God's providence, where even evil intentions are used by God for good. The trajectory of Joseph's life—from being sold into slavery to becoming a ruler—demonstrates that God orchestrates all events to fulfill His redemptive purposes. This is a cornerstone of sovereign grace theology, affirming that God's plan is unthwarted and ultimately leads to salvation.
