In I John 2:20-27, we find three things we can use to defend against the deception of antichrists.
Knowledge of the Truth
Every believer has received an anointing of the Spirit that enables us to understand the truth of God’s Word. No believer has “special access” over others into truth.
We must use this truth to identify the lies of the spirit of antichrist. This illustration may seem trite, but it is well-known that when bank tellers are trained to identify counterfeit money, they are thoroughly educated in what the genuine article looks like. Thus, if a bill doesn’t match up with what they know to be authentic, they reject it as being a deception.
The same principle should apply to believers when trying to discern doctrine. We should be so thoroughly familiar with who Christ is as revealed in Scripture, that when a false presentation of Jesus is brought before us, we are immediately aware that it is heresy.
Continuing in Doctrine
We cannot allow the basic doctrines of Christ to be forgotten. These are the very bedrock upon which our faith rests. Regardless of variations within our systems of theology, all true believers base their doctrine upon who Christ is.
I believe that this should cause us to frequently review the words of Christ. We should stay grounded in His teachings so that we will not falter in our doctrine. This will also enable us to recognize an “imposter” Christ. Without exception, every cult in existence has strayed from the truth concerning the person of Christ.
Take Personal Responsibility for Learning the Truth
The anointing of the Spirit remains in every believer. This is the “Spirit of truth” which was promised to us by Jesus, himself. This renders every believer capable of discerning truth. May I suggest that in this case capability equals responsibility? I believe that we are required by God to know the truth.
Too many Christians are content to learn the truth vicariously. They are perfectly willing to ignore their Bibles, instead relying upon their pastor, teacher, or the latest book to fill their minds with the doctrine of Christ. There is no substitute for a Spirit-led believer opening the Word of God and laboring over a text until the meaning is ingrained in their heart.
In short, the Antidote to Antichrists is TRUTH. Know it and you will be free.
