Mark 13:31

29even so you also, when you see these things coming to pass, know that it is near, at the doors.

30Most certainly I say to you, this generation will not pass away until all these things happen.

31Heaven and earth will pass away, but my words will not pass away.

32“But of that day or that hour no one knows—not even the angels in heaven, nor the Son, but only the Father.

33Watch, keep alert, and pray; for you don’t know when the time is.
