Benefits of Wudhu

I came across this Hadith today from a yahoo group I am subscribed to. It is about the benefits of Wudhu. I myself am a bit reluctant to perform the Wudhu and often pray Asr and Magrib prayers with one Wudhu. I see no reason why I should do that now.

Abu Huraira reported: Allah’s Messenger (may peace be upon him) said: When a bondsman-a Muslim or a believer-washes his face (in course of ablution), every sin he contemplated with his eyes, will be washed away from his face along with water, or with the last drop of water; when he washes his hands, every sin they wrought will be effaced from his hands with the water, or with the last drop of water; and when he washes his feet, every sin towards which his feet have walked will be washed away with the water or with the last drop of water with the result that he comes out pure from all sins.
