1. I am plenty enough familiar with Scripture. As I explained before, it’s about those who aren’t.
2. As bb pointed out before, combining passages of Scripture to make them say something they don’t lacks integrity. My opinion is that it more than smacks of dishonesty.
3. Irrelevant.
4. No and also irrelevant. It’s simply a convenient system for reverencing passages of Scripture so people don’t waste their time looking for it.
For the record, you have rarely even posted the BOOK of the Bible the passages are found in.
If you have gone to the trouble of finding the passages of Scripture yourself to post them, it takes precious little extra effort to add the reference so that people both know that the words are not mine and that they can find them easily if they wish to investigate further. And I DO know that. I do it all the time.
It’s simply common courtesy, thinking of someone besides yourself.
