What does the Bible say about the role of miracles?

In Scripture, miracles are often depicted not merely as extraordinary acts but as divine revelations that confirm Jesus' identity as the Messiah. They were particularly significant during the transition from the Old Covenant to the New Covenant, serving to authenticate the message of Jesus as the Son of God. As stated in John 4:48, Jesus remarked that the people needed signs to believe, indicating that miracles served as a bridge to faith. However, the purpose of these miracles extended beyond the acts themselves; they aimed to point to the truth of the Gospel, leading people to recognize and embrace Christ as their Savior. Today, while miracles may still occur, their primary role is not to serve as the basis for faith; rather, the fullness of the Word of God provides the revelation intended to guide believers.
