> The daily struggle of a Christian is to strive to rid one's self of their sinful desires (selfish / evil) and live as Christ commands. This a continual process, and one that cannot be stopped. If one just "gets tired" of being a Christian, and lives differently, then they are in danger of losing their salvation.

How is this not a vehicle of control? It steers you in the direction of behaving the way Christianity prescribes for fear of the ultimate bad consequence which is losing your salvation.
