Why search for God?

There are many guides on "how to seek union with the Divine". Anything from prayer, to meditation, to trance, to DMT is suggested. Each religion has their own method of course but suprisingly all seem to agree that this "search for God" is a good thing, something to be encouraged...

What I never understood is why...? Why is it such a good thing to search for God?

Let's assume that we do have an eternal soul and that we can attain union with the Divine....

If our purpose were to be "one with the Divine" then we would not have been put on earth in a material body in the first place, right?

Ok, so if being one with God is not the purpose of our earthly life then what is? The experience of desperately trying to attain the immaterial with our physical bodies? Why even try when we will be immaterial once we die anyway?

So, what is our purpose then? Perhaps to focus on the material...? That would make "seeking the Divine" obsolete and in fact counterproductive...

And still, where you or I ever to find the 'divine', what would really change? (instead of having a mental assurance that our life is probably purposeful although no one can really tell us why exactly). I would still need to feed my stomach and drag my sad, fat ass over to the toilet afterwards...

I guess then that it is has no "higher purpose"... It is just good if you like it, that's all.
