He looked up and saw rich people putting their gifts into the treasury; he also saw a poor widow put in two small copper coins.  He said, "Truly I tell you, this poor widow has put in more than all of them; for all of them have contributed out of their abundance, but she out of her poverty has put in all she had to live on."

Clearly we are not being commanded to give away all the money we have to live on, such that we then depend on the welfare of others to live.  Those who breath a sigh of relief here, thinking they don't have to part with their wealth, have little love of God in their hearts.  Jesus does not gaze at money, he gazes at people's hearts.  Shall we try to please God by our generosity with money?

If one offered for love

all the wealth of his house,

it would be utterly scorned.  (Song of Songs 8.7)

Love gives all, true love is reckless.  It not only gives all and pines to have more to give, it arduously seeks to cast far from it things which keep it from the beloved.  It abandons itself to love by wanting to become completely dependent on the beloved - yes, even to the point of life itself.
