28 "Now learn the parable from the fig tree : when its branch has already become tender and puts forth its leaves , you know that summer is near . 29 "Even so , you too , when you see these things happening , recognize that He is near , right at the door . 30 "Truly I say to you, this generation will not pass away until all these things take place . 31 "Heaven and earth will pass away , but My words will not pass away . 32 " But of that day or hour no one knows , not even the angels in heaven , nor the Son , but the Father alone. 33 "Take heed , keep on the alert ; for you do not know when the appointed time will come . 34 " It is like a man away on a journey , who upon leaving his house and putting his slaves in charge , assigning to each one his task , also commanded the doorkeeper to stay on the alert . 35 "Therefore , be on the alert -for you do not know when the master of the house is coming , whether in the evening , at midnight , or when the rooster crows , or in the morning - 36 in case he should come suddenly and find you asleep . 37 "What I say to you I say to all , ' Be on the alert !'
