The church of God is like the Internet. The Internet is a massive worldwide organism, connecting the secret blogger in China's computer with the businessman in Russia with the teenager in Madrid with the Facebook-playing housewife in New Hampshire. Although they do not see each other and will never meet, the things they do online daily change and evolve the Internet, and they all share a connection which transcends all races, boundaries, cultures, and time zones.
In the same way, the Church is a connection of millions of individual humans from around the world. We are all logged in - but instead of using WiFi or cabling to connect each other, we are connected by the Spirit of God. And make no mistake - just like the Internet, everything you do in life will affect the Christians on the other side of the globe...even if you never meet. Why? Because you share in an intimate connection, a higher ideal which binds you spiritually - transcending all races, boundaries, cultures, and time zones.
Just like the Internet, the Church has revolutionized the world for the good. And just like the Internet, the Church is filled with perversions and spam and viruses, flawed programming of flawed minds. Just as we do with email, we in the Church must be careful to avoid those who--using the Church as their commercial endeavor--peddle false doctrine to make us feel good or to cause a virus to enter our local system. The Internet has penis-enlargement spam; the Church has the 'name it and claim it' heresy. Both feast on the same weaknesses (desire to improve yourself with regard to your acceptance in this world), and both are spread using similar techniques.
And just like with computing, a local area network is often very helpful (though perhaps not strictly necessary) to success. Getting connected to a local body of Christians can help you get through the tough times, set up a tougher firewall against the viruses, and share in the things that are common both to your faith and to your cultural struggles.
