I guess, the degree of commitment needs to also enter into the conversation.

And at times it may appear different depending upon the context ...or upon the varying connotations of how to define words such as sacrifice.

A sacrifice:

• The act of giving up something that you want to keep especially in order to get or do something else ...or to help someone.  
• To give up something that is valuable to you in order to help another person.  An example often used is when women sacrifice interesting careers for their families.
• A loss or something you give up, usually for the sake of a better cause.  It can be said that parents sacrifice time and sleep to take care of their children.

That sacrifice of soldiers committed to serving in the military for the cause of protecting our freedoms (often involving loss of life, or sustaining  injuries which impair them for life) is a service to all of us which too often gets criticized, instead of receiving our grateful appreciation. 

But, let's go back to another sacrifice: that of Cain and Abel.

Then the Lord said to Cain, “Why are you angry? Why is your face downcast? If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”  

There seems to be a definite motivation why Cain's sacrifice wasn't what it was supposed to be ...and God approached him with encouragement and a way to improve.

Let's go back further than that even ...to the sacrifice that was made to supply skins for Adam & Eve, so they would be covered.

Several generations later, with many centuries passing, Noah and his family spent nearly a hundred years building the ark ...time and effort was spent, among much ridicule. That would also be considered a great undertaking ...or sacrifice.

After the flood, and after much babbling ...a time came for a man to be led far away from his people. Abraham was later asked to sacrifice his son ...something God did not have him do, nor do I believe He would ever ask anyone to sacrifice their son.  It was setting the stage of emotions for the day when Jesus would be a sacrifice for us ...for our sins.  No act stands as great as that sacrifice. 

What do we do ...aside from accepting what He did on Calvary??

Number #1 answer:  Tell others about Jesus.
