I.e., as a conscious, selfless offering in His name of something that one cherishes as necessary and valuable, and not as an attempt to "propitiate" Him who is far above anything that resembles human emotion. (See also verse {36} below.)
This is the true end of sacrifice, not propitiation of higher powers, for Allah is One, and He does not delight in flesh or blood (xxii. 37), but a symbol of thanksgiving to Allah by sharing meat with fellow-men. The solemn pronouncement of Allah's name over the sacrifice is an essential part of the rite.
The good news: i.e. the Message of Allah, that He will accept in us the sacrifice of self for the benefit of our fellow-men.
