How do we know that Jesus can grant mercy?

In Matthew 15:21-28, we see a poignant example of the power of Christ to grant mercy. The Canaanite woman approaches Jesus, desperate for mercy for her demon-possessed daughter. Despite initial silence and the suggestion that it was not fitting to give the children's bread to dogs, her persistent faith and plea for mercy compel Jesus to respond affirmatively. This narrative powerfully illustrates that Jesus, knowing the depths of human need, responds to those who seek Him earnestly. His ability to grant mercy is not based on human merit but on His sovereign grace, demonstrating that He is willing to help those who recognize their need for Him.
