The verse speaks of the miraculous signs that will follow those who believe in Jesus. These signs are not just extraordinary events but are manifestations of the divine power that believers have access to through faith. Driving out demons signifies the authority over evil that believers possess, reflecting the victory of Jesus over darkness. Speaking in new tongues represents the diverse and inclusive nature of the Christian faith, as well as the ability to communicate the gospel across different cultures and languages.
This promise of signs is not limited to the early church but extends to all believers, suggesting that faith in Jesus brings with it a dynamic and active spiritual life. These signs serve as a testament to the living presence of God in the world, working through those who believe. The passage encourages believers to embrace their spiritual gifts and to act with courage and faith, knowing that they are empowered by the Holy Spirit to make a difference in the world.
