One big thing to note: "do not believe in every spirit." Um, okay.
Really, the speaker just means that people and ideas might seem like they're from God, but they're not. You've got to put these folks to the test.
The test involves making sure these people and ideas center on the fact that Jesus came "in the flesh." That just means that it's important to believe Jesus was a human being and not just some divine being who only looked like a human. Or an android. Jesus was definitely not an android…
The author says that lots of false prophets and antichrists are peddling some old nonsense about Jesus (hint: the speaker is calling out the folks who have broken off from the community). These guys are "from the world," which means they care about ordinary non-godly things. And you'll remember from 1 John 2 that this is…bad. Very bad.
Now we're back to love again.
The speaker tells the audience that they should love each other because "God is love." If you have love in your heart then you're living how God wants you to.
The speaker says that God loved the world so very much that he sent Jesus. Jesus gave up his life so that people could have a sin-free relationship with God.
And because God loves humans a ton, the author continues, we should love each other. Really, it's the least we can do.
No one has ever seen God face to face, but when we love each other, we show the world what he looks like. It's very poetic.
Simple recipe from the author:
Step 1: Believe that God sent Jesus to save the whole world.
Step 2: Love your fellow Christians.
If you're filled with love, there's no reason to be afraid about the end of the world, says the speaker. Unless, of course, you read the Book of Revelation.
He finishes off the chapter by saying that if you go around saying that you love God but you're hating on other Christians, then you're just a liar.
