How was Noah to be a comfort?

Dear cook4t7, obviously it was Lamech, Noah's father, who saw in his son a great comfort (or repose, as it also can be interpreted), someone who would be a relief in the hard labor they had to do in order to get sufficient food out of the soil. Ancient Hebrews named their children according to the expectations they put into them. Nevertheless, many reformed theologians take Noah as a "type" of Christ, a kind of symbol that anticipates the future fulfillmente in the New Testament. In this sense we see Noah as the beginning of a new humanity (but with the old failures), like Christ is the beginning of a truly new humanity. And Christ is our true repose and comfort.

Well with all the wicked people on earth at that time that were multiplying at a rapid rate, having someone who followed God would certainly be a comfort since his father would have assumed that God might remove the curse because of that. Also at the time, he did not know that God would later wipe all the wicked men, women, and children off the Earth later on. He may have figured that Noah, a righteous man would have turned the hearts of the people other than his family to God. And when the Flood came, Noah was a comfort since Christ was considered in his ancestry and Christ is a comfort to the believers.
