So we are commanded to preach to all nations, all people, even though we cannot communicate to all nations since they speak different languages. This is a tall order and somewhat a difficult task... Especially if you don't speak every language.
GM28 for iPhone, iPod touch, and iPad on the iTunes App Store
Stop now and go and download it! It is really amazing it has a built in questionnaire, a preaching mate and the Gospel presentation. Just select which one you plan on using and then select what language you need to present in and hit play. It will read outloud through the speaker in the language you selected. You have Dutch, English, French, German, Italian, Japanese, Mandarin, Russian, Spanish Castillian, Spanish Neutral and Turkish to choose from.
You could use this tool with your headset on Xbox Live for those parties when you hear another language and wish you could share. Not only does it vocalize it for you through the speakers but it puts it on the screen too, so you can see how to type it!
I highly recommend downloading and giving this a try its that easy! Not only that but it might give you the words in english to help build your confidence and learn how to share as commanded in the Great Commission, the way Jesus did it...
Get out there, get bold, call on God to help you share your faith, plant seeds or water them and leave the rest up to God.
