Jeff Randall,
I don't know what you have witnessed overseas. I know Christian missionaries are humans and will do wrong things, no doubt about it. True that knives will help people in this life, but missionaries that are true Christians (maybe you've seen some who weren't), are doing the most nobel of works. they are spreading the message of salvation in Christ, and Christ alone. They are fulfilling what the mission of all us Christians is. Giving someone a knife is nice, but leading someone to the saving knowledge of the true and living God, and in essence eternal life, well - that has eternal significance. It takes very special and comitted Christians to answer the call of God (take up their cross and follow Him). To go live in foreign countries (most of them third world countries), leave their families, friends, and luxuries, that we all take for granted, and go live amongst other peoples in other countries, with other cultures, learn their language, endure unending hardships and often persecution; sometimes unto death - just to share the Truth (Jesus Christ) with them, is one of the nobelest of callings. And they are definitely worthy of our support - both financially and in prayer.
Many, many, Christian missionaries have given their lives as martyrs overseas. More than you could ever imagine. Your comments are an insult to their loved ones they have left behind.
I am sorry you have witnessed people who you thought to be Christians harming others. I assure you one thing, if you saw people harming others, they were neither missionaries, nor were they Christian.
Peace,
Dennis
