It is not everything that God tells you that you should tell others. There are certain things God tells you that are for your ears only.
God likes to share secrets with those that are close to Him. If He tells you a secret, you should ask Him if it is okay to share it with anyone.
Prophecies must be handled with care because some people might not be able to receive, understand, and interpret what God is saying correctly.
When God tells you something about a particular fellow, you are not to say that thing in public except He specifically asks you to do so.
“Our God is not a gossip. If He gives you information about someone, it is not for you to discuss it with the whole world. Isaiah 38:1-5. If instead of telling the fellow privately, you announced the prophecy to the whole world, if God changes His mind, you will be left to defend what you had prophesied.”
MEMORISE: He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction. (Proverbs 13:3)
