Heb 11:7 By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith.
Noah having recieved an oracle from GOD in which he was told to build an ark. This ark was the first that ever was in the world. There was to be entrance of all creatures into it two of every kind male and female. They were to be preserved in it as well as Noah and all his family. It was also to be the destruction of all that were not to be in the ark~all without it~the wicked!
This Divine Warning concerning these things was delivered to Noah and received by him showing he was favored of GOD. That his faith rested in the Word of God that was spoken to him.
Noah moved with fear not of his own damnation or distrust of the salvation of himself and his family in the ark but with an awful sense of the judgments of God upon the wicked; and with reverence of God, from whom he received the oracle; and with a religious fear, with which he worshipped God.
Immediately, and without delay, he set about the building of the ark, and made it exactly according to the pattern which was given him.
And his end in it was to secure his family, himself and his wife, his three sons and their wives, from the flood, which he believed would shortly come upon the world, according to the word of God.
And in this his faith was seen: and from this it may be observed,that as God saved Noah and his family in the waters, so he can, and does, save his people in afflictions; and also, that true faith is attended with obedience.
The inhabitants of the world, the world of the ungodly: as a preacher, he declared they would be condemned, in case of unrepentance and unbelief; and his words heard, and his actions seen by them, were aggravations of their condemnation.
For by his works, as well as by his words, he reproved, and condemned them; by building the ark, as he declared his own faith, so he condemned their unbelief.
