3. The Holy Spirit Converts Us: It is through the Holy Spirit that Christians are born again. John 3:3 says that a man cannot see the kingdom of God unless he is born again, and this process is made possible by the Holy Spirit. The Holy Spirit is also crucial to a Christian’s ability to live life as a new creation in Christ.
4. The Holy Spirit is a Person: Some religions think of the Holy Spirit as less than a person. However, the Holy Spirit is a vitally important person when it comes to the Christian life. Romans 8:26 talks about how the Holy Spirit intercedes for Christians, which is just one of the many roles the Holy Spirit fulfills.
