The Holy Bible introduces us to concepts which theologians sometimes call "metaphysical" concepts. These are concepts generally of "being and knowing" which are not based on "hard physical science." They include Biblical concepts like those of spirit, soul, heaven, hell, angels, demons, Satan, the Almighty God, etc. In short, the so-called "metaphysical" concepts include all to which the Bible refers as "things which are not seen." The scripture further informs us, "For the things which are seen are temporal, but the things which are not seen are eternal." (2ndCorinthians 4:18). It is with things "eternal" and "not seen," things which cannot be discerned with the five senses of the fleshly body, which I am concerned in this study. Instead of the term "metaphysical things," however, I prefer to use the Biblical term "spiritual things," as does Paul in Romans 15:27.
