1 John 4:2-5

2Hereby ye know the Spirit of 1God: every spirit which confesses Jesus Christ come in flesh is of 2God;

3and every spirit which does not confess Jesus Christ come in flesh is not of 3God: and this is that [power] of the antichrist, [of] which ye have heard that it comes, and now it is already in the world.

4Ye are of 4God, children, and have overcome them, because greater is he that [is] in you than he that [is] in the world.

5They are of the world; for this reason they speak [as] of the world, and the world hears them.
