I always provide a source link if I use another person's work. I also do not see how truth changes between what I say versus what another believer says. Is the truth all of a sudden different because someone else said it? Besides, Jesus did the same thing. He spoke really long at the Sermon on the Mount and they were not His own words; For Jesus was speaking everything that His Father told Him to say. God's Word itself is written by men but yet inspired by another author.
The words Jesus spoke were given by the Father, not a webmaster that often turns out to be behind a cult. The men that wrote his words were inspired of God-breathed words that cannot fail.
I prefer to quote scriptures whenever needed to support a statement I write, though surely not needed this moment, yet.
Most of the time, people do not check out links unless it is something they are really interested in. I have many times have gotten responses on things that I quoted in an article. So I know this form of posting works.
If you quote something other than scripture I always either click on your link or search the phrase. Whatever comes up, I investigate before replying. I'll often do a search on the webmaster's name, or chase down clues in their pages. Not saying you use their resources, but often I've found quotes here that originated from a site that is based off another site that is based on JW's Watchtower or maybe SDA, RCC, Mormon, and others.
People do not like it because they are into thinking of writing like the world thinks of writing. If you do not provide your own original content then it is not worthy of them to read. As if truth changes if it is provided by another. Are we truly interested in truth? Or are we out to impress each other with how we write nice original (but yet not so original) posts. Does throwing a new coat of paint accross a post really change what is written? I say thee nay.
Some people are into writing like the world thinks of writing. I don't think of someone changing truth by what they write, as that's not logical, nor reasonable. Many people want to sort out false from truth, but don't know where to start.
I don't claim to be inspired of God like Matthew or John was when they wrote scripture. I do believe that by study of the Bible and prayer, and trusting that the Holy Spirit still gives me the right words to say or write is valid for me. If the Spirit gives it, while someone else rejects it, they can't possibly be listening to the same Spirit.
That applies to me. How do I know which is right? Not the credentials of a webmaster, but by the word of God. So of course what he might give me So of course my "paint" could definitely change the message of what someone else has written of their own thoughts, or those of someone else they have probably never met, not can they truly find out their background, as with most of us here. So we have to mostly go by content, how it checks out with the Bible.
