Many people today want to discuss "are we in the end times?' It is not a fruitless conversation, because when it is pondered correctly then Scripture is being read and discussed. And any time the Word of God is read, discussed, and focused on God can do good things with it. But Jesus Himself says that no person will know when He will return until the time comes.
The Day and Hour Unknown
32 “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. 33 Be on guard! Be alert! You do not know when that time will come. 34 It’s like a man going away: He leaves his house and puts his servants in charge, each with their assigned task, and tells the one at the door to keep watch.
35 “Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. 36 If he comes suddenly, do not let him find you sleeping. 37 What I say to you, I say to everyone: ‘Watch!’”
