What does the Bible say about signs and wonders?

In the book of Acts, particularly chapter 5, signs and wonders are recorded as miraculous works performed by the apostles under the sovereign authority of God. These events served to validate the apostles' messages and demonstrate God's power. For instance, many miraculous healings were attributed to the shadow of Peter, indicating that these wonders were meant to draw attention to the gospel rather than to the individuals performing them. Importantly, once the New Testament canon was complete, these signs ceased, as they were specifically appointed for the early church's establishment and the verification of the apostolic teachings.
