How do we know God's grace was at work in Rahab's life?

God’s grace is clearly at work in Rahab’s life through her recognition of the one true God and her faithful actions despite her background as a harlot. Rahab stated, 'For the Lord your God, he is God in heaven above and in earth beneath,' signifying her acknowledgment of Yahweh’s sovereignty. This understanding was not merely intellectual; it was coupled with a desire for salvation, which reflects the transformative nature of God’s grace. God's choice to include Rahab in His redemptive plan, even as a Canaanite woman, illustrates His grace that transcends human limitations and societal barriers, affirming the truth that 'God's plans work together for good' throughout Scripture.
