You CAN lose what you DO have!
1 John 5:13
I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.
Take your argument up with JOHN!
I have zero argument with John.
His first epistle is what I rely upon for clear revelation of Yeshua’s Way.
Those that do so will know that they have eternal life, because they keep all of Yeshua’s words, all of his Torah, because he has written it on their hearts.
That is exactly what John is saying in 1John 5:13.
