2 Thessalonians 2:2-3

2Please do not become easily confused about this. Do not let yourselves become afraid because of false messages about the Lord's return. Some people are telling you that the great day of the Lord's return has already happened. Some of these people say that God's Spirit has shown them a message like that. Other people might say that the message came from us. Or they might say that we wrote it in a letter.

3Do not let anyone deceive you like that in any way. That day will not happen until certain other things have happened. Before that day, there will be a time when many people will turn against God. Also, the man who is completely against God will appear. God will surely destroy him in the end.
