1 John 2:20-21

20But you have an anointing from the Holy One [you have been set apart, specially gifted and prepared by the Holy Spirit], and all of you know [the truth because He teaches us, illuminates our minds, and guards us from error].

21I have not written to you because you do not know the truth, but because you do know it, and because no lie [nothing false, no deception] is of the truth.
