1. Noah who preached the Christ, the ark of salvation (Heb 11:7)
    2 Pt 2:5, Jn 3:18, Jn 5:22, 1 Pt 3:20-22

Noah warned that those who did not obey God’s word would be judged. To obey God’s Word is to believe in the coming Christ. (Heb 11:7, 2 Pt 2:5)

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.

2 Pt 2:5 And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;

What Noah’s Flood signified was the baptism of dying with Christ and rising again with Christ. The flood is a sign of salvation for those who believe in Jesus as the Christ, and a sign of destruction for those who do not believe in Jesus as the Christ. (1 Pt 3:20-22)

1 Pt 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:
22 Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him.

Those who do not believe that Jesus is the Christ have already been judged and will be judged forever. (Jn 3:18, Jn 5:22)

Jn 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

Jn 5:22 For the Father judgeth no man, but hath committed all judgment unto the Son:
