What does the Bible say about miracles and wonders?

In the New Testament, miracles and wonders serve as signs pointing to the true identity of Jesus as the Son of God. In Acts 15:12, Paul and Barnabas recount the miracles performed among the Gentiles, emphasizing that these were acts of God's grace that confirmed the gospel's validity. Throughout the gospels, we see miracles performed by Jesus that demonstrate His control over nature, sickness, and even death, affirming His divine nature. For instance, He calms storms, heals the sick, and raises the dead, actions that only God can undertake. These miracles serve not only to meet immediate physical needs but primarily to reveal His authority and invite faith in His saving power.
