Perception

I have a thought that we never do something entirely for ourselves. I believe that what we do is always in accordance with what someone else wants. Meaning, we have two choices. What society wants, and what God wants. (always the case, yes?)

If we are mortally depressed and we decide that we want to broadcast this to the world via blog or AIM, what is our purpose? We know of our own depression, so these messages of depravity must be for others. We want people to know of our saddness. Why? Why are we so intent on sharing our misery with others? Is it for comfort..selfish gain..self-promotion? In any case, it is for other poeple to know, the action we took part in was for someone else besides ourselves.
The motive may be for self gain, but the action was purely for general consumption.
Even as far as people self-promoting themselves as Christians for societal views would not be in accordance with the moral right, yes? It probably depends on the individuals heart. If we perform an action with the right mindset (God) and not an action done out of vanity, it would be good.
Jeremiah 17:10
10 "I the LORD search the heart
and examine the mind,
to reward a man according to his conduct,
according to what his deeds deserve."
God gave us the choice for humility to counter-act vanity faith. He wants us to have the right motive AND the right action.
Please correct if wrong.
