If you want people to take you seriously, really seriously; just ensure you're especially skillful at telling LIES. Because you can't possibly "prosper" in the eyes of men by strictly telling people the TRUTH.

Noah did not prosper according to men's wisdom, neither was Jesus (see how many fled from Jesus himself in John 6:66, except his 12 disciples), and Paul (2 Tim. 4:10). These sought heavenly treasures above all else. Imagine a great man of God with just SEVEN (7) members in his church (ark), do we call that prosperity?  Who would believe that a great flood would destroy the whole of mankind, except those that would choose to enter the ark?

Remember:
Matt.7.14 - But the gateway to life is small, and the road is narrow, and only a FEW ever find it.

Likewise, it can be even more difficult for us today to believe in what is called the Rapture: the second coming of Jesus (to come after the GREAT tribulation of the Antichrist); and the great Judgement coming upon the world. (2 Thes. 2:3-12)

Honestly, just like the time of Noah, how many do truly believe that God is going to judge the world, and destroy this present world with FIRE?

2Pet.3.7 - And God has also commanded that the heavens and the earth will be CONSUMED BY FIRE on the day of judgment, when ungodly people will perish.

2Pet.3.10 - But the day of the Lord will come as unexpectedly as a THIEF. Then the heavens will PASS AWAY with a terrible noise, and everything in them will "DISAPPEAR IN FIRE", and the earth and everything on it will be exposed to JUDGMENT.

About this time last year, who would believe that some sort of PANDEMIC would come and SHAKE THE WHOLE world, especially if it was mentioned by a man of God after the order of "bro Noah" (NOT of Pastor Judas or Prophet Balaam, though)?

It would be wise for us to learn from the painful mistakes of the people of Noah's time and of many others of OLD times, and be SAVED from the coming WRATH of God (Matt. 3:7/Luke 3:7).

Gen.6.13 - And God said unto Noah, The END of all flesh is come before me; for the earth is "filled" with VIOLENCE through them; and, behold, I will DESTROY them with the earth.

Luke.17.26 - And as it was in the days of Noah, SO IT WILL BE ALSO IN THE DAYS of the Son of Man (the Rapture):

Luke.17.27 - 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.

Entering the Ark today is more about being truly repentant and obedient to Jesus; NOT necessarily about having some sort of loyalty to, or acceptance of a Church or some great Pastors/Prophets.

Matt.24.37 - "When the Son of Man RETURNS, it will be like it was in Noah's day.

Matt.24.25 - See, I have WARNED you beforehand.

The grace of Jesus be with you.

Heb.11.7 - It was by faith that Noah built an ark to save his family from the flood. He OBEYED God, who WARNED him about something that had never happened before. By his faith he CONDEMNED the rest of the world and was made right in God's sight.
