When I was little, really little. Like six or seven, I was taught never to trust in man, only God. So I was most surprised when in Genesis 6:5-8, it says
5 The LORD saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually. 6 And the LORD regretted that he had made man on the earth, and it grieved him to his heart. 7 So the LORD said, “I will blot out man whom I have created from the face of the land, man and animals and creeping things and birds of the heavens, for I am sorry that I have made them.” 8 But Noah found favor in the eyes of the LORD.
Obviously what I was being taught even at that young age was biblical.
And then when Jesus said it about us, man as well.
even when he is old he will not depart from it.
