Why is the religion seen as the somewhat Godly entity (to 'that' religious follower). Religion is an 'organisation of truth' a collection of writings. People join a religion, and you cannot wholly blame the religion for the way the person is, but blame the way the person is directly.
Most people join religion either through needing a sense of belonging (group psychology), or because of cultural or family persuasion, sometimes forced (especially in Muslim countries).
Under the above circumstances, people will often follow like sheep in false teachings which may well be 'mainstream', especially in how to operate within your religion, which pretty much always includes the idolisation of the 'central character' of that religion. How else are they going to keep you, if you can think for yourself and therefore are free?
Was is Jesus that said "Idolise me"?
Why does a young girl become a Bieber fan? Is it because she has a belief in his goodness or wants to know him? No, it is often a sense of belonging, it is often the cultural norm of those around her own circumstances. But what does she do, does she idolise this person? Yes. Does she get to know or understand him as a real person? No.
And this is similar to many who follow religion. Idolisation is highly destructive and is most visible when people put a subject of religion on a pedestal. Religion often tries to bring about an idolisation of it's central character, because it hooks people to that religion, somewhat condemning all others, it is religious submission.
There are good people in Islam, there are bad people in Christianity. What I am saying in the previous sentence, is that often as a Christian, people think that there are bad people in Islam, and there are good people in Christianity.
How does religion have such a control over people to define whether they are good or bad? A bad person sees bad and yet chooses to continue regardless, a good person often makes the tough choice of change when they see bad, regardless of suffering (the harder option).
Either way, we have free will to follow like sheep, or to question everything. If you question nothing, well, does that only happen in Christianity? What does it do when people question nothing in Islam while idolising their central figure?
Not only that, but people most often idolise their 'book of texts'. In fact they idolise their physical book of texts most often more than they idolise the central figure. Often no-one dares question this and anything written in it, even if written in times when man was more carnal. I mean, that's just logical right? Well apparently not if you question it.
To sum it up, more than idolisation:
The goal of this command is love, which comes from a pure heart and a good conscience and a sincere faith.
