Moshiach will be a small change that will make a huge difference.
People sometimes dismiss the whole concept because it seems too radical to envision flying on eagles' wings and all the world knowing G-d. But really, with all the technology that's escalating so rapidly, we CAN imagine it. 'Google Now' unites all the parts of my life and that reminds me of how achdus Hashem will be rampant throughout the world. One message you post on a social network and millions upon millions of people can receive it instantly. These are real things, part of our life, but we see em through Golus glasses. We outta see em through Redemption Lenses.
May the Beis Hamikdosh be built speedily in our days, amen!!
