Gen 7:7, Psalm 46:1-3, Matthew 11:28, John 14:6, Matthew 24:38-39, Luke 17:26-27, 1 Peter 3:20-21

Noah and his family entered the ark and were saved. (Genesis 7:1,7, 1 Peter 3:20-21)

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. 7 And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.

1 Peter 3:20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. 21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:

God is our refuge and salvation. (Psalm 46:1-3)

Psalm 46:1 God is our refuge and strength, a very present help in trouble. 2 Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea; 3 Though the waters thereof roar and be troubled, though the mountains shake with the swelling thereof. Selah.

Jesus, the Christ, is the way of salvation and the eternal refuge. (John 14:6, Matt 11:28)

John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

Matt 11:28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.

Everyone except Noah and Noah's family did not realize that they could be saved only in the ark, so they all perished. Likewise, all who do not believe in Jesus as the Christ will be judged. (Matthew 24:38-39, Luke 17:26-27)

Matthew 24:38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, 39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.

Luke 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man. 27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.
