He,
maybe the best for you is to export now that content (Tools/Export in your WordPress Dashboard) and save it on your hard drive and next time just import that content. For other users this work good. If you want to get preview in front page just select it in Customize. Go to your General tab/Static pages, check “A static page” and for front page select Home or some other page that you want to set to be in front.
We are glad to help :)
Cheers
