Temples are the greatest because they are a place were families are seal together for time and all eternity. In the temples, people who hold authority from God to be able to bind families on earth so they will be bound in heaven. The blessing that come from having a family who are ALL going in the same direction, together is like no other. I love my family and there is no one else I would rather be next to them my family.
I would challenge you all to go find a temple that is close and then go and feel the spirit that is just around the temple. If you don't know much about the temples click on the picture and it will take you to the Latter Day Saint website that does a better job at explaining temple then I do.
