Once Christians receive the the Holy Spirit in their lives,they receive spiritual gifts that prove the validity of Jesus' teachings.
1 Corinthians 12:8-10
8Some of us can speak with wisdom, while others can speak with knowledge, but these gifts come from the same Spirit. 9To others the Spirit has given great faith or the power to heal the sick 10or the power to work mighty miracles. Some of us are prophets, and some of us recognize when God's Spirit is present. Others can speak different kinds of languages, and still others can tell what these languages mean. :close look:
