Luke 4:18 says, “The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor.
Here in this Gospel written by the Apostle Luke; the greek word for Spirit is pneuma. It has the meaning of spirit, wind, to blow, to plant; spiritual, spiritually, God-breathed, inspired by God.
In Jewish thought, pneuma can be described as that power which enables human beings to relate to the spiritual realm, the realm of reality which exist beyond human observation and control.
Pneuma is used in the NT more than 250 times in reference to the Spirit of God, the Holy Spirit, and spiritual power, wherein God is it’s source.
Likewise, pneuma is used about 40 times in reference to human being belonging to, and interacting with the spiritual realm.
