There are two terms used in the Bible for "spirit". The word "ruwach" in the Hebrew means wind, breath, mind or spirit. It is used 378 times in the Old Testament and is translated "spirit" 232 times. It is also the Hebrew word for wind and breath, it is translated as wind 92 times and as breath 27 times. It is translated 9 times in direct connection with personal actions or traits, such as mind, anger and courage. Its root word means to smell, touch, understand or accept.
The word "pneuma" in the Greek, means a spirit or being. It can also mean breath or wind. The root word "pneo" means blow or wind, or to breath. It is the Greek equivalent of the word "ruwach." But "pneuma" unlike its Hebrew equivalent of the 385 times it is used in the NT it is used in conjunction with a person or being or to refer to personality and translated as "spirit" it reefers to traits or personal action more than 360 times.
Below are just a few examples of how the word "spirit" is used. These all indicate that a spirit is not just a form of power but denotes personality. The examples from the Old Testament use the word "ruwach" for spirit, the examples from the New Testament use "pneuma". Note that many of the passages that these verses are taken from are not being written in figurative language. Those that are refer to personal feelings.

The Spirit teaches. 1 Corinthians 2:13
The Spirit can be lied to: Acts 5:3
You can attempt to tempt the Spirit Acts 5:9
(You can blaspheme the Holy Spirit)
Matthew 12:31
Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
It seems odd that God would forgive all manner of sin and blasphemy, even against his own Son, but not forgive it against an impersonal active force akin to a holy electrical charge, unless the Holy Spirit is indeed a person.
In truth there does not need to be an assumption about the personal nature of the Spirit, for many places in the Bible declare it clearly and in non-metaphorical, literal terms. In order to believe that the Spirit is not personal we have to disregard the many places where the Spirit of God and other spirits are shown to be persons, in favor of an assumption that the nature of a spirit is only a force. That is not reasonable.
