Remembering that technology is a tool and not a teacher, Google has a lot of tools that can be used to help organize your classes and bring the world into your classroom.
Google EarthGoogle Earth can give you a virtual journey to any location in the world. You can create a virtual tour of the Holy Land, the journeys of Paul, and explore 3D buildings, imagery, and terrain. It's amazing what you can see with this satellite imagery. See the terrain and make the places Jesus walked real!
Google+ HangoutsA hangout is a place where you and (up to) 9 others can have a live video chat using a variety of devices. If you have a small class and can't be available one week, you can connect in a hangout. It's also a perfect way to have a guest speaker who isn't local.
