GENESIS 6:5

And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.

GENESIS 8:21

And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.

For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be. Matthew 24:38, 39

Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these things God will bring thee into judgment. Therefore remove sorrow from thy heart, and put away evil from thy flesh: for childhood and youth are vanity. Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them; Ecclesiastes 12:9-13:1
