The fundamental gift of Christ is a continued existence beyond our mortal death, for the asking I might add. We all fall victim to evil and the sins of this existence. Jesus sacrificed himself to rescue us from this world, not that we may all be governors.
Render unto Caesar that which is Caesar's, is merely a statement to the difference.
“That which is Caesar’s” is that which is of the Earth, and thus irrelevent WRT eternity.
It can be really tough to let go of it though.
