Most of scripture is parables, it's the way God hides His word from the world... that's why there is so much division in the church.
Please, do you understand them and are you practicing them in your own life, and you know in knowledge spirit, this parable speak in relation to the New Covenant given to Christians, who are saved, 'by Grace through faith', the gift of GOD, for 'a jump start', and 'abide' through the words of CHRIST of the New Covenant, 'the author and finisher of our faith', are able to find their way home, which is a 'difficult to follow' way and 'only a few will make it' home of 'GOD's place of rest' in Heaven.
These words of 'spirit' and 'life' Spiritual knowledge, as it is already been written for all Christian to witness as sound doctrine knowledge and also called to be a witness who are also living them, 'practice' and 'impart' to an ignorant world and also to an ignorant Christians, actually speaks to those who acknowledge and repent not to those who reject and perish and also perish again.
This was what Noah was saying what GOD said to him and he was saying to others and when they rejected and when Noah got saved, he was not enjoying, but became a drunkard, because of their ignorant to what GOD had said earlier in warning.
Because finally he lost most of his relatives and friends and also others as a community to be saved by the rescue of GOD, which is the 'ark' of salvation for that day, given only to righteous Noah, by GOD..
