How far should we go?

How far is too much? I realize that, as a Christian, I am not to think of myself, to place myself last and serve others first. I do this because our example on the life we are to live, Jesus, told us that this is how we are supposed to live and modeled that way of life for us while He was here on Earth.

But, does there come a time when serving others becomes presenting myself as a welcome mat for others to walk on? Is there a difference? I mean Jesus served with all He had, including His life, for all of us. There were also times when He expressed indignation and anger (think confronting Pharisees and overturning tables in the temple courts).

Now, I enjoy serving people around me. But, when those same loved ones and friends do not acknowledge that service for what it is and only see my actions as being a pushover, is that counter-productive? I know all of the thoughts that our way of addressing the world will be seen as weak to begin with because we have different ways of viewing life and our reason for being here and what we have to look forward to at a later time. I have no issue with that expectation, but, is there a line that is too far?

Just some random musings and thoughts, but I would like to hear feedback on this one.
