I spent about an hour watching a famous woman speak on PBS to women about personal wealth. Generally, I usually read or listen when this woman talks, because she is usually knowledgable about financial planning. She spoke to her audience about a flaw that women usually have--they give and give without getting something back from it. Later, she picks "generousity" as one of several characteristics of a wealthy woman--that it is alright to give as long as the woman is also just as generous to herself, or if she gets something out of the act of giving.
She also exhorts the crowd of ladies that "you are not on sale", that they need to value themselves and what they do; to not give themselves, their talents or their time away for free. And probably after listening to the financial woes of many women, both stay at home moms and business women, I'm sure she has a reason to say what she does. Women are good at sacrificing, almost too good.
And women feel guilty, especially if they feel that they have been selfish in saying "no" to a request. Or "stop" to a system that isn't doing them any favors. Or if they hadn't given enough to make everyone happy. Or if they make others jealous or resentful because of their successes.
And, if for once, they have to think of themselves first for a change. From where I stand, it's hard to find that boundary. That balance.
"Do nothing from selfishness or empty conceit, but with humility of mind
let each of you regard one another as more important than himself; do not merely
look out for your own personal interests, but also for the interests of
others." Phil. 2:3-4
A lot of what happens for the glory of God is done by Himself alone, sometimes He will use people if He wants. Is the glory of God selfish? No, we are all helped by His glory. We need it like we need air to breathe, food to eat and clothes to wear.
