The Story

1 John is a letter soaked in two words: love and truth. False teachers (early Gnostics) were denying that Jesus came in the flesh and claiming secret spiritual knowledge. John's test is simple: Do you believe Jesus came in real flesh? Do you love your brothers and sisters? Do you obey God's commands? If yes, you can have assurance — you really do know God. "God is love" appears here, and so does "God is light." You can't claim to be in the light while walking in darkness or claim to love God while hating your neighbor.

How to know if your faith is real

John gives you three tests: Do you believe in Jesus? Do you obey God's commands? Do you love other people? That's it. Not complicated, but not easy either. First John strips away all the religious noise and gets to the core: God is love, God is light, and if you know Him, it will show in how you treat others.

If the evidence of knowing God is loving others, how strong is your case?
