How do we know that Jesus has power over evil?

In the Gospel, we often see Jesus engaging with and overcoming evil forces. In Matthew 15, the woman begged Jesus for help for her daughter, who was grievously vexed by a devil. When Jesus finally responds to her plea, He asserts His authority by proclaiming that her faith has made her daughter whole. This instance not only showcases Christ's power over demonic forces but also emphasizes that He is capable of addressing the most difficult and complex problems faced by humanity. As believers, we can take comfort in knowing that there is nothing too hard for the Lord (Jeremiah 32:17).
