1 John 2:18-20,25-27

18 Little children, these are the end times, and as you heard that the Antichrist is coming, even now many antichrists have arisen. By this we know that it is the end times.  19 They went out from us, but they didn't belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us.  20 You have an anointing from the Holy One, and you know the truth. 

25 This is the promise which he promised us, the eternal life.  26 These things I have written to you concerning those who would lead you astray.  27 As for you, the anointing which you received from him remains in you, and you don't need for anyone to teach you. But as his anointing teaches you concerning all things, and is true, and is no lie, and even as it taught you, you will remain in him.
