What does the Bible say about faith and persistence?

In Matthew 15:21-28, we see a powerful example of faith and persistence in the Canaanite woman who cried out to Jesus for help. Despite being initially ignored and called a 'dog,' she persisted in her plea, demonstrating importunity—an insistence and determination that ultimately led to her daughter's healing. This story illustrates that true faith often involves unwavering persistence and the belief that even a small blessing from God is sufficient. Her determination shows us that faith is not merely passive belief but an active pursuit of Christ, proving that those who seek Him will find mercy and grace.
