“Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world. This is how we know if they have the Spirit of God: If a person claiming to be a prophet acknowledges that Jesus Christ came in a real body, that person has the Spirit of God. But if someone claims to be a prophet and does not acknowledge the truth about Jesus, that person is not from God. Such a person has the spirit of the Antichrist, which you heard is coming into the world and indeed is already here.”
1 John 4:1-3 NLT
Discern what others are saying. We haft to ask questions, so that we may know the truth. There’s many false teachers in the world and John notes that there part of the anti-Christs plan or deceiving with him. So fellow believers do not be deceived, for satan wants us to do so. But be ready for your faith to be questioned by those who do not believe in a Christ’s sacrifice or the trinity. We are to be on guard and ready for those arrows to fly towards us. We must be fully equipped for battle. So stay vigilant, meditate in the word and wrap it around your hearts and minds.
