Very good post, brother David. Some years ago I added this topical study to my other studies. I used my Young's Analyical Concordance, and wrote down every scripture in the New Testament that mentioned 'one another'.
I wish all the brethren were taught more fully on these scriptures. We are to be closer than a blood family...i.e., our kinfolks.
Our little congregation is that way, except for one family that will practically attack you if you say anything that their immediate family does/did is wrong.
They apparently do not understand what Jesus said about " if anyone loves mother, father, sister, brother, son or daughter more then Me, they are not worthy of Me."
We are having a problem with this, because one granddaughter, who does not even attend our meetings, (and I am not sure she attends anywhere), is being payed by our congregation to clean our building, and she has fallen way down on her duties. 'We' are afraid to approach her, or her mother, or her granddmother about it, because they would become very angry at anyone who did so. I am not sure about her uncle, he may be more open to having it pointed out to him.
Sorry if I took this off-topic.
But do you have any suggestions?
