Maybe this will help- John 13:35
“By this all men will know that you are My disciples, if you have love for one another.”
Your verse is Jesus during His 3.5 yrs of ministry to the Jews.
So, at this time Jesus had not died on The Cross Yet, so, there were no CHRISTIANS yet.
This is why your verse is talking about "DISCIPLES".......and not CHRISTians.
Jesus explains that a DISCIPLE is "if you keep my words".... John 8:31
Whereas a Christian , is a SON-Daughter of GOD< who is BORN AGAIN.
A Disciple may not be a Christian.
John speaks about brothers/brethren.......who were """false""".....and said....>>"they went out from us, but they are not OF US">
In other words they are disciples and "jewish brothers".....to John,.......... but they are not Christians.
One of the Things about John, and James, and Peter, is that their ministry was to the JEWS.
So, it can be confusing to some readers of the NT, when these 3 talk about brethren, and brothers, and they are not taking about Christians in the verse.....they are speaking from the Jewish standpoint regarding other Jews.
On Forums like this one......you find a lot of cult members who believe they are Christians........because their cult has them believing it.
But when you pin them down and demand they explain how they became a Christian......all you get is "water baptism" and "commandment keeping" and "self effort".
They can't talk about The Cross of Christ where they were saved, because they've not been there yet.
A Christian is BORN AGAIN, and has the Spirit of God in them.
THat is how you know they are a True "Brethren".
Some are clever and will pretend even that.... but their Salvation Denies they are born again.
I agree with you that many are not born again. I also blame the forum for allowing every brand of religion to tag as Christian.. That would cut it down quite a bit. Not totally, but it would make for a lot less strife and nonsense. I have brought it to their attention- they don't care.
2 Things cause "christian" Forum strife to never end.
#1 is allowing non-Christians who pretend they are Christians, to "teach theology" all day and all night.
#2, is that there are certain topics that always cause fighting, so, if the forum will stop allowing these few Topics to become "Threads".. then that eliminates 95% of the stfife on a forum.
The issue is, the Mods like these topics and many members only come to Fourms to fight about these topics.
Eliminate these Topics from being posted as Threads, and a Chrisitan forum calms down 90%
1.) OSAS
2.) The Trinity
3.) Water Baptism
4.) Losing Salvation
5.) Pre-destination
6.) Replacement Theology
7.) Errors in the Bible.
