He said love Him with all our heart, mind, soul and strength as well.

Someone is always trying to shrink the message, minimizing the love they have to give God and their neighbor. 

He doesn't want very much from us...just our all.  And when one looks at "our all" as not very much, one begins to understand humility, and we're able to make EVEN GREATER gifts of ourselves..because we no longer 'count the costs". 

No shrinking of the word of God. 

In fact Pope just this morning said: "Pray, and When Things Become Dark, Pray More"
