re: looking for a sign.
"Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee." Rev. 3:3
as an aside, The Jews call the first day of the Feast of Tabernacles the day no one knows, because the watchmen would sit up all night looking to see if the moon appeared. If any of them fell asleep on the job, a priest would set their clothes on fire and they would go home naked and ashamed.
I think you hit the generation right on the head.
As for seeing the signs:
Luke 21:25 "And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; 26 men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken. 27 And then shall they see the Son of man coming in a cloud with power and great glory. 28 And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh. 29 And he spake to them a parable; Behold the fig tree, and all the trees; 30 When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand. 31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
32 Verily I say unto you, This generation shall not pass away, till all be fulfilled...
36 Watch ye therefore, and pray always, that ye be may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man."
In Revelation 5, the redeemed sing, Only you are worthy Lord Jesus to receive Blessing, and glory, and wisdom, and thanksgiving, and honor
"Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing."
Thank you, Lord, for what you have done, and for what you will do.
