As with every other religious group who
claim to be Christian, I believe that there are some who genuinely are, and some who really (perhaps unknowingly) are not. It is not about what they say, it's about the life they live... and we are
commanded to exhort eachother to see the truth of this matter, and to try to turn the sinner back to His Lord (see
James 5:19-20)
Christ said "
If you love me, obey my commandments." John 14:15; and speaking through the Holy Spirit, John said "
Those who have been born into God's family do not make a practice of sinning, because God's life is in them. So they can't keep on sinning, because they are children of God." 1st John 3:9.
I haven't fellowshipped with the Amish; although my time in fellowship with Hutterites (a sect very closely related to the Amish) has shown me that there are many on these colonies who do walk with the Lord, and love His Word. There are also many I've met there who are cold and indifferent; it is the same everywhere, even in the LC. As Igzy said, all we can do is preach the gospel and pray that the Lord has mercy.
For those doubting that Christ can reach the Amish, I ask you to remember another school shooting not long ago, in your country. It took place at Nickel Mines school in Pennsylvania, on October 2nd 2006. The gunman took hostages, and shot 10 girls, ages 6-13. He killed five, before he turned the gun on himself. How the Amish parents of those little girls reacted showed Christ to your nation... and that reality is more powerful than any testimony any man can voice. Here's a clip of the story that made the news....
