“The opposite of Antichrist is Discipleship” 

One of very key things Jesus said to the Jews which believed in Him, for which that word stands for how we can recognize who a disciple is, is the word “Continue in My Word” 

John  8:31 Then said Jesus to those Jews which believed on him, IF YE CONTINUE IN MY WORD, THEN ARE YE MY DISCIPLES INDEED;

The word CONTINUE here means to ABIDE, so He said to continue in His word shows we are His disciples. We see ABIDE being used as CONTINUE 

John  15:4  ABIDE IN ME, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye ABIDE IN ME.

We see in a place where the word “ABIDE” was used then the word “CONTINUE” comes out with it. 

1 John  2:24  Let that therefore ABIDE in you, which ye have HEARD from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father.

What did they heard from the beginning which they must abide in? It was the word

1 John  1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the WORD OF LIFE;

So let’s go back to that scripture it says 

 “…If ye CONTINUE IN MY WORD, then are ye my DISCIPLES indeed;

Now, this is the point we are hitting at, let’s see what John said in his Epistle

1 John  2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.

2:19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have CONTINUED WITH US: but they went out, that they might be made manifest that they were not all of us.

What does the Apostle mean here?  Remember he said this…

1 John  1:3 That which we have seen and heard declare we unto you, that ye also may have FELLOWSHIP WITH US: and truly OUR FELLOWSHIP IS WITH THE FATHER, AND WITH HIS SON JESUS CHRIST.

Clearly we see that the Apostle said the Antichrist went out from us but they are not of us. He now said if they have been of us, they will no doubt CONTINUE with us because is like, a disconnection from us is a disconnection from the Father, as they continue in us in fellowship because our fellowship is with the Father we also are His disciples because we continue in His word. What distinguish the Antichrist from the Disciples is the ability to continue in the word, in the Father and in the Son Jesus Christ and also to continue with fellowship with the believers.
