Trauma is a side-effect of events that happen to us which are beyond our control. None of us can ever plan for such events and by their very nature we are always unprepared for them.
There can be both short-term and long-term consequences of traumatic events. How we are affected by them can depend on a wide range of factors. An incident which may have been very traumatic for one person could be of little consequence to another.
God created us with spirit, soul and body. In 1 Thessalonians 5:23 Paul expresses concern that his readers should be whole in all three. While we may use the words spirit, soul and body to describe three distinct and different aspects of what God created when he made mankind, in reality whatever happens to one part affects the other.
It is impossible for one part of our humanity to experience anything which the other parts are not also involved in or affected by! Be compassionate you truly never know the trauma someone has suffered silently.
