Mark 13:28-33

“Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see these things happening, you know that it is near, right at the door. Truly I tell you, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away. “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. Be on guard! Be alert! You do not know when that time will come.
