Not everything that claims to speak for God is trustworthy. Followers of Christ are instructed to discern carefully any person or source that claims authority, checking them against what scripture teaches. If a claim doesn’t pass the test then avoid it.
In 1 John it says not all spirits are trustworthy, and we should test each spirit to make sure it comes from God
Also, when God speaks to us His word says: "And the peace of God, which passes all understanding, shall keep your hearts and minds through Christ Jesus." Philippians 4:7 -- So there is a Godly peace that pervades your being when He speaks to you.
