It's not about it following CEV but people believing it, that it acts in their best interest. Reasons are subordinate. It is the similar systematic of positive and negative incentive that I wanted to highlight.

I grew up in a family of Jehovah's Witnesses. I can assure you that all believed this to be the case.

Faith is considered the way to happiness.

Positive incentive:

“O you who believe! What is the matter with you, that, when you are asked to go forth in the Cause of Allâh, you cling heavily to the earth? Do you prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter.”

Whoever does right, whether male or female, and is a believer, We will make him live a good life, and We will award them their reward for the best of what they used to do. (Quran, 16:97)

Negative incentive:

"You dissipated the good things you had in your worldly life and enjoyed yourself in it. So today you are being repaid with the punishment of humiliation for being arrogant in the Earth without any right and for being deviators." (Surat al-Ahqaf: 20)

I could find heaps of arguments for Christianity that highlight the same believe of God knowing what's the best for you and the world. This is what most people on this planet believe and this is also the underpinning of the rapture of the nerds.
