Jesus does not need to nor does He rely on mythical events in order to make comparisons concerning the time of His return at His Second Coming. He uses actual historical events.
Jesus spoke of the flood as literal history and He also spoke of Lot and the destruction of Sodom as literal history because He compared those two historical time periods to the future time period of His own return. In other words, people will continue to sin and so they will be judged when He returns again at His Second Coming just as judgment came to those sinful persons in Noah’s time and in Lot’s time.
Luke 17:27-29
They ate, they drank, they married wives, they were given in marriage,
until the day that Noah entered the ark, and the flood came and destroyed them all. 28
Likewise as it was also in the days of Lot: They ate, they drank, they bought, they sold, they planted, they built; 29 but on the day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed them all. 30
Even so will it be in the day when the Son of Man is revealed.
Peter also spoke of it as literal history when he explained that the flood was a precursor to Baptism. The ark saved Noah and his family (saved through water) and the earth was cleansed by the flood waters.
Baptism now saves us (saves us through Baptismal water) by applying the merits of Jesus’ blood sacrifice to our souls. This sacrament cleanses us from Original Sin and gives us justification of life because of the sanctifying grace which we received through Baptism. (
Romans 5:6-19)
1 Peter 3:19-21
by whom also He went and preached to the spirits in prison, 20 who formerly were disobedient, when once the Divine longsuffering waited
in the days of Noah, while the ark was being prepared, in which a few, that is,
eight souls, were saved through water. 21 There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ,
Jesus went to preach to the poor souls in purgatory (spirits in prison) while He was in the grave awaiting His own resurrection. These “spirits in prison” are the people who repented while they were drowning in the flood. They were in purgatory for about 2000 years already before Jesus went to preach to them because Noah’s lifespan occurred about 2000 years before Jesus was born. 2000 years is a long time (according to our thinking and counting time) to be imprisoned in purgatory, but these poor souls were extremely thankful to be saved.
The waters of Baptism are not like bath water because bath water only cleanses our bodies of dirt, but the waters of Baptism cleanse our souls of Original Sin and thereby give us reconciliation to God (a good conscience toward God). Baptism regenerates us spiritually by removing Original Sin from our souls and we then become the temples of the Holy Spirit who gives us sanctifying/saving grace as long as He abides in our souls. If we sin deadly/mortal sins, then the Holy Spirit moves out and we lose our sanctifying grace since He is the provider of sanctifying grace and we must have sanctifying/saving grace in our souls when we die in order to be saved. (
1 Corinthians 3:16-18,
1 Corinthians 6:8-10,
Ephesians 5:3-6)
Titus 3:5
not by works of righteousness which we have done, but according to His mercy He saved us, through the
washing of regeneration and renewing of the Holy Spirit,
This refers to water Baptism. The waters of the Sacrament of Baptism wash our souls clean from all the sin that is on our souls at the time of our Baptisms and this washing regenerates us spiritually and makes us adopted children of God because the Holy Spirit moves into our souls and makes us His temples.
If we sin deadly sins after Baptism, we are then cut off the Vine who is Jesus, and we are no longer saved because the branch cannot have life without the Vine. (
John 15:1-7) But, if we confess and repent of these sins, then we can be grafted back onto the Vine and become saved again. Sanctifying grace will be restored to our souls when we confess and repent.
Romans 11:22-23
Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off. 23 And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.
