How do we know prayer for deliverance from evil is true?

We know that prayer for deliverance from evil is true based on Christ's instruction. In Matthew 6:13, He teaches us to pray, 'Lead us not into temptation, but deliver us from evil.' This directive illustrates Christ's acknowledgment of the reality of evil and temptation in our lives. Furthermore, in John 17:15, He expresses the desire not for removal from the world, but for believers to be kept from evil. Thus, through Christ's teaching and His emphasis on the necessity of such prayers, we can be assured of their validity and necessity in our spiritual lives.
