FMF hoping to ferment division among Christian brothers does his best.
If you are a follower of Protestantism then, according to sonship, you are a follower of a "Satanic organization".
The Bible says that
"the whole world lies in the evil one" (1 John 5:19). Yet out from it we can be saved and brought into His eternal purpose.
So any organization overly influenced by God's enemy is not an impediment to His salvation. Otherwise no one would have any hope.
sonship wants you to join his cult.
You do not join the universal church in that sense. You are regenerated into it. You are spiritually born in the church universal.
I have already "joined" the brother by entering into Christ just as he has - through regeneration - through being born of God.
That Christians would see something about local ground of the practical church? Sure, I wish all brothers would see something more there. That is as God permits.
His "kind words" may well simply be him trying to prey on you as one of the more weakminded Christians here.
FMF hates that two Christians would have fellowship, even briefly.
To assure there is no fellowship he gossips to turn one against the other saying I think he is weakminded. On the contrary. The OP was strong minded in the truth of God's word.
The weakminded one is FMF, for he has no solid rock to stand on.
His standing in quicksand is postured as him not being here to take a position on any major life questions, but to question why others follow Christ.
He shows some signs of having received training on manipulating either potential cult members or bullying errant cult members.
So if you greet another Christian brother, you have been trained in manipulating for a prospective cult membership and bullying.
This is FMF hatred to see two different Christians simply greet one another, knowing full well that they may have some different understandings of things.
When like FMF you have nothing to stand on you have to divide others who both show signs of standing on a rock - Christ and His word.
Gimmicks and logical fallacies and rhetorical tricks and constant casual dishonesty. Do you remember the Witness Lee books he said you ought to read in order to avoid "damnation"?
The verses in the OP were quite adaquate in speaking to eternal salvation.
The gimmick is FMF trying to introduce a red herring that instead of the verses I insist people read some book by Witness Lee.
Best book on avoiding the damnation is called
"The New Testament". There are many good translations of this book. I like the Recovery Version which study version contains footnotes by Brother Witness Lee.
Ryrie's, MaCarther's, Amplified, Emphasized, Scoffield, Dakes, Darby's, Weymouth's, and other adequate English language translations of the New Testament are also good. I'm sure other good ones will come in the future.
I recommend the RcV -
Recovery Version as the most up-to-date in present age light from the Holy Spirit to the church universal.
