When its branch has already become tender and puts forth its leaves, you know that summer is near. Even so, you too, when you see these things happening, recognize that He is near, right at the door. Truly I say to you, this generation will not pass away until all these things take place. Heaven and earth will pass away, but My words will not pass away. But of that day or hour no one knows, not even the angels in heaven, nor the Son, but the Father alone.
