The one who believes in the Son of Elohim has the witness in himself, the one who does not believe Elohim has made Him a liar, because he has not believed the witness that Elohim has given concerning His Son.
I have written this to you who believe in the Name of the Son of Elohim, so that you know that you possess everlasting life, and so that you believe in the Name of the Son of Elohim.
And we know that the Son of Elohim has come and has given us an understanding, so that we might know the true One. And we are in the true One, in His Son יהושע Messiah. This is the true Elohim and everlasting life.
So if I come, I shall call to mind his works which he does, babbling against us with wicked words. And not satisfied with that, he himself does not receive the brothers, and forbids those who wish to, putting them out of the assembly.
