I think one has to first define what is meant by the question. What does he mean by 'fully occupy the gospel'?
If, as I believe, you think he means 'live you life fully obeying the teachings therein', we have a further difficulty, in that different denominations/groups within denominations interpret those teachings in radically different ways.
Putting these little local difficulties aside, and looking at the broader picture, it would shake up a lot of the establishment, both political and economical.
