Avoid Spiritual Vertigo

Looking at things from a different perspective can be a frightening and unsettling thing because we do not know where it will lead us, and potentially upsetting of personal relationships.  Even scholarly people tend to 'play safe' and stay within their ‘comfort zone.’  It would be too costly for them to go outside the ‘received wisdom,’ so what invariably happens is that the same old thinking tends to be regurgitated over and over again with no new or fresh thinking impacting on or providing clarity to the precious truths of the Gospel.  
This is particularly true when dealing with the atonement.  It is not so much a matter of us dealing with the atonement but rather the atonement taking a radical dealing with us.  Approaching such a divinely-charged doctrine slays ‘the old man’’ and the ‘old nature’ in man, a situation that can cause theological dizziness and spiritual vertigo.  So to avoid this some Christian thinkers prefer to stay safe, delve into the unrevealed mysteries that God has kept to Himself,  and not scale the heights of revealed religion.
