The word “spirit” comes from the words “breath” or “wind” because both are expressing an existence of something we cannot see but understand its power. And when Jesus explained to his disciples about the Holy Spirit he emphasized the connection and difference between the Spirit and the Flesh. For example: In John 3:5-7, Jesus told Nicodemus, a religious leader who was trying to understand the teachings of Jesus that
5 Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. 6 Flesh gives birth to flesh, but the Spirit[a] gives birth to spirit. 7 You should not be surprised at my saying, ‘You[b] must be born again”.
Therefore when the Holy Spirit comes into a person, he imparts the life of God and makes the person.
According to John 15:26, the Holy Spirit is sent by Jesus, from the Father, to dwell in a person. “When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—he will testify about me”. The Holy Spirit is God that is working with the Father and the Son.
The Holy Spirit makes the difference between being religious, but spiritually dead, and being religious and spiritually alive. The spirit, therefore, brings spiritual life. According to Romans 8:9, “You, however, are not in the realm of the flesh but are in the realm of the Spirit; if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ”. In Ephesians 5:18, St. Paul said that the Holy Spirit can fill us. This understanding is also available in Acts 2:4, 4:8, 31; 9:17; and 13:51. Even though our current life can feel like it’s situated in the physical, there is more. Once we begin having a spiritual lifestyle, God is able to work with the Spirit and save us from sins.
We should, therefore, seek for the Holy Spirit’s power at all times.
