Hello, I believe this passage needs a better translation that would clarify what is said in the Bible itself.
1 John 4:1
Names of God Bible
Test People Who Say They Have God’s Spirit
4 Dear friends, don’t believe all people who say that they have the Spirit. Instead, test them. See whether the spirit they have is from God, because there are many false prophets in the world.
This passage is a warning of how in final days many will simply announce that they are the Messiah/Christ and fool many, Matthew 24:23–26. God alone is the Messiah and created a body that will come to earth and provide all the needs spoken through the Prophets, Hebrews 10:5 and Revelation 12:1–2. What important prophecy will be fulfilled at the Second Coming of Christ and the End of the World?
John 4:25
Living Bible
25 The woman said, “Well, at least I know that the Messiah will come—the one they call Christ—and when he does, he will explain everything to us.”
