How do we know that miracles serve as signs of God's kingdom?

The miracles of Jesus serve as powerful signs of the coming of God's kingdom. In Luke 11:20, Jesus states, 'But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you.' This statement indicates that His works are evidence of God's reign breaking through into human history. Each miracle, like the casting out of the demon from the mute man, was a direct confrontation to the reality of sin and Satan's dominion. They not only displayed Jesus’ divine authority but also illustrated the transformative nature of God's kingdom, which seeks to heal and restore humanity. Therefore, these miracles are not isolated events but rather divine signs pointing to the eschatological reality of God's kingdom.
