I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. (1 John 1:21 ESV)
We bemoan the decay of truth in our society, and we should. What is worse than the world redefining and denying the existence of any absolute truth, however, is when truth is denied in the church. We are well aware of the manifold heresies that plague the professing church today. None of this is new, however.
In the first century, deceivers and false brethren plotted to steal the sheep away from the Shepherd. These were antichrists, whom John’s audience heard “is coming” and “now many antichrists have come” (v18). In fact, the very existence of these men proved that it was “the last hour” (v18). The antichrists were denying the Father by denying the Son (v22-23) and trying to deceive believers (v26). Add to those charges the tragedy that they came not from without, but from within the very fold they were trying to deceive (v19), and we can relate to the fears and anxieties of first century Christians.
But John, by the inspiration of the Spirit, is not aiming to leave his readers in despondency. In fact, even as he warns of antichrists, John’s disposition is not one of doom and gloom but of hope and encouragement. He refers to his recipients as “children”, writing from a pastor’s heart. He writes of a sharp contrast between those antichrists and the true believers: they have denied the faith, but you know the truth. He encourages them by reminding them of who they are and what they have in Christ: “you have been anointed by the Holy One” (v20), “you have all knowledge” (v20), “you know [the truth]” (v21), you have the “promise that he made to us – eternal life”, and the anointing “abides in you” and “teaches you about everything” and “is true” (27).
What, then, shall we do when it seems truth is crumbling all around us? Abide. Remain. Stay the course. “Let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father.” (v24) It’s not the coming of the antichrist that should grab our attention, but the coming of the Son of God. He is the one we aim to please, looking for him with joyful expectation and confidence. How do we have this confidence? Abide. Remain. Stay the course. “Abide in him, so that when he appears we may have confidence and not shrink from him in shame at his coming.” (v28)
