1 Thessalonians 5:1 - 2: "Now, brothers, about times and dates we do not need to write to you, 2 for you know very well that the day of the Lord will come like a thief in the night..."(NIV)
I am beyond frustrated with groups who claim to know the day and hour of Jesus' return. Jesus himself said "But about that day and hour, no one knows, not even the angels in Heaven, nor the Son, but only the Father." (Matthew 24:36, NIV) I believe Jesus is coming back - I just don't know when. It could be today, tomorrow, or 500 years from now.
Earlier this evening I read an article about the man who predicted the "doomsday" this past weekend. He is now stating he was about five months off and it will occur in October.
Please do not be deceived by false prophets. If someone says they have a word from the Lord or they have solved some theological mystery, then listen to it and test it. First John 4:1 says "My dear friends, don't believe everything you hear. Carefully weigh and examine what people tell you. Not everyone who talks about God comes from God. There are a lot of lying preachers loose in the world." (The Message)
