Why did people stop worshipping God after experiencing the flood? I have just started reading Genesis and have a question about Noah's family. If Noah and his family were the only people left on earth after the flood, why did most of the world forget God and worship other gods, like in Asia and Africa? After being blessed and allowed to live by God, I would think that Noah's family would make sure God's story was passed down through all generations (and parts of the world).
The same way it was lost in the first place.

For the same reason that Cain killed Abel.

Noah was saved physically from the physical calamity, but he was not regenerated. He was not yet saved from sin. He was still a sinful creature as were the other members of his family. The promise from Genesis 3:15 was not yet fulfilled.

The Bible and indeed all of human history is full of the same story. It does not really matter how earth shattering a miracle is witnessed or how clearly people know that God did something (up to and including saving their hides), we all still turn away from God. It's a heart problem.

In Exodus you will find a people that in the course of one lifetime saw God repeatedly intervene on their behalf and they repeatedly turned against him.

The message of the Bible is that you and I are that people.

The solution is still forthcoming. It is found in Christ, but it's a work in progress—secured and completed at the cross but still being revealed to us today. The destruction of the corrupt earth in Noah's day and Noah's being brought over into a new creation was a TYPE or pattern of salvation: a symbol of how the real thing would be but it was not the real thing. You will find in the New Testament that the flood story is a kind of baptism.


  1 Peter 3:20-21 (ESV)
  20&nbsp; because they formerly did not obey, when God's patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water. 21&nbsp; Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ,


Just as baptism is a physical symbol of being cleansed  and the reality that we will be resurrected with Christ yet it does not make us perfect or stop us from sinning, so the flood was a symbol of the same thing but it did not fix the heart problem. It didn't end the sin-nature of man.

One day, the destruction and re-creation that was foreshadowed in the flood (and in baptism) will be completed for real.


  Matthew 24:37 (ESV)
  37&nbsp; For as were the days of Noah, so will be the coming of the Son of Man.


The corrupt wicked world that has rejected God will be judged and destroyed and God's people—the ones he chooses to save—will be brought into a the new heavens and new earth only this time with a our natures renewed to what Adam's should have been. Only then will there be a world that is imperishable and incorruptible.

What you expected to have happen after the flood will happen, but the flood was only a precursor to the real thing.
