In a speech to a crowd of 9,000 at a Phil Waldrep ministry event, former President George W. Bush said that he missed being the Commander-in-Chief most of all:

I miss being commander and chief of our military the most. You know you live in an amazing country when we have servicemen that continually volunteer to serve their country in the face of danger. I believe we have an obligation to give our troops all the support they need to accomplish their missions.

He spoke for an hour on faith, patriotism, and his time in office.  In giving his reasons for choosing a portrait of Abraham Lincoln for the Oval Office, Bush said 

[Lincoln] believed that all men were created equal under God even during times of civil war. He believed in the spirit of freedom. I believe in God Almighty and that everyone desires to be free and want peace.

Despite those that criticized him as an overtly Christian President, Bush said that ensuring religious freedom is one of the hallmarks of America:

The President of the United States should never promote a particular religion…That’s just another thing that makes us such a great nation, being able to worship God as we choose.
