The body is the material part of man, the part that can be seen by the mortal eye. At death, we know the physical body returns to dust (Genesis 3:19). It is totally destroyed and is not resurrected (see Acts 2:27-29; 13:24-26; Ecclesiastes 9:5,6,10; Job 14:7-10; Job 34:14,15). The resurrected body of soul and spirit is not a physical body.
The body as God created it was 'very good', but through the 'fall' was contaminated by 'evil'. The evil is in the blood. It is the blood that keeps our physical bodies alive (see Romans 7:23,24; Leviticus 17:11). In this life, there is a curse on the body that it shall return to dust (see Genesis 3:19) but Scripture tells us that the covenant of death shall be disannulled, and the agreement with hell shall not stand (see Isaiah 28:18; Hosea 13:14; Isaiah 25:8).
While the spirit is non-physical and the body physical, the soul acts as an interface between them whilst the body is alive. The living conscious mind (soul) has continuing awareness of the physical world, but at times it gains insight into the spiritual non-material world (see 1 Corinthians 2:14). These insights or gifts of understanding can vary enormously from person to person.
