“I have written these things to you about those who are trying to deceive you.” ‭‭1 John‬ ‭2:26‬ ‭HCSB‬‬

What things?

Do not love the world or the things of this world, verses 15-17.

The antichrist does not belong to us, verses 18-23.

Cling to eternal life, verses 24-26.

Why does John need to write these things? Because all these things are what can distract us from the gospel of Jesus. 

The world wants us to conform to their standards and be ineffective for Jesus. The antichrists what us to tone down the blood of Jesus and include “many ways” to God. Eternal life is our main objective for living this life now.

“Therefore, brothers, by the mercies of God, I urge you to present your bodies as a living sacrifice, holy and pleasing to God; this is your spiritual worship. Do not be conformed to this age, but be transformed by the renewing of your mind, so that you may discern what is the good, pleasing, and perfect will of God.”

‭‭Romans‬ ‭12:1-2‬ ‭HCSB‬‬

“Adulteresses! Don’t you know that friendship with the world is hostility toward God? So whoever wants to be the world’s friend becomes God’s enemy.”
