I know this is a seeming tiny point and compared to the whole bible, seemingly unimportant, however, since the Bible is the Inspired Word of God, all that is in it is very important. Out of the study of one small point can come Gold, like panning for gold nuggets in a river.
Revelation from God out of His Word can come from the seemingly slightest point.
The Holy Spirit must be a person, like Jesus is a person, and the Father is a person.
Its’ difficult to see Him this way, because we don’t have ‘other’ things about Him to relate Him too, the way the father image and the son image have mental pictures of what a father and a son is to relate that too.
The Holy Spirit or Holy Ghost, we only have ‘ghost’ mental pictures to relate to that.
Although they are joined, 3, in One, they are also individual Persons.
I’m just saying that Jesus’ Spirit is not necessarily the Holy Spirit, since Jesus and the Holy Spirit are two individual Persons joined in the Godhead, yet still individual as far as Person is concerned.
If you think of the Holy Spirit as an individual Person in the Godhead, you can see what I am trying to say.
