How does the story of Jericho illustrate God's grace?

The account of Jericho's conquest vividly depicts God's grace through the lens of His mercy towards Rahab, an outsider and perceived unworthy. Despite her background as a harlot, God's election and sovereign choice allowed her to recognize her need for salvation. This parallels the Reformed understanding that salvation is by grace alone; it is God's sovereign will that extends mercy and forgiveness to those who believe, regardless of their past failures. Thus, the salvation of Rahab is held as a testament to the unmerited favor found in God.
