Did Methuselah Drown? Maybe! The oldest man on record, Methuselah, lived to be 969 years old. He was Noah’s grandfather. He died in the year of the flood.
Were The Wicked Warned? I think so. The prophet Enoch warned them (Jude 14-15). Noah was a preacher of righteousness (2 Peter 2:5). Also, God’s Spirit did strive with them (Genesis 6:3). A prophet, a preacher and the Spirit of God, but no revival.
Why Did Noah Find Grace? Genesis 6:6-9 gives us three reasons. Noah was a just man, perfect in his generations and he walked with God. A just man – one who esteems what is right – I believe gets God’s attention. Noah was not only just but walked with God – found his fellowship with God. He also was perfect in his generations – his family history. This may mean that his lineage could be traced back to Adam through Seth, without being touched by the lineage of those created on the sixth day (see the article, Were Adam And Eve the First Persons?). Noah is called a preacher of righteousness in 2 Peter 2:5.
Did It Take 120 Years to Build The Ark? No! Genesis 6:3 refers to 120 years but not in reference to building the ark. God told Noah to build the ark and to include his sons and their wives in the deliverance. It seems Noah had three married sons at that time (Genesis 6:10-18). Shem was 97, possibly 98, when the flood came (Genesis 11:10). Therefore the building time was much less than 120 years.
Were They In The Ark For 40 Days? No! It rained for 40 days and 40 nights (Genesis 7:12), but they were in the ark for over a year (Genesis 7:11 & 8:13-14).
