Genesis 7:1 And the Lord said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation. 4 For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.
These passages depict not only justice, but mercy and love to the human family, with the very best of interest for all in mind. In fact, if God did not destroy the antediluvian world when He did, no one would be alive today, and the human race would have long ago become entirely extinct. Several specifics about the antediluvian make this crystal clear.
[Patriarchs And Prophets pp 91>99] Polygamy had been early introduced, contrary to the divine arrangement at the beginning. The Lord gave to Adam one wife, showing His order in that respect. But after the Fall, men chose to follow their own sinful desires; and as the result, crime and wretchedness rapidly increased. Neither the marriage relation nor the rights of property were respected. Whosoever coveted the wives or the possessions of his neighbor, took them by force, and men exulted in their deeds of violence.
They delighted in destroying the life of animals; and the use of flesh for food rendered them still more cruel and bloodthirsty, until they came to regard human life with astonishing indifference. As sin became general, it appeared less and less sinful, and they finally declared that the divine law was no longer in force. The altars on which human sacrifices had been offered were torn down, and the worshipers were made to tremble at the power of the living God, and to know that it was their corruption and idolatry which had called down their destruction.
2nd Peter 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. 10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
May The Lord add His blessing to the study of His word. God bless!
