The Signs of the End Time as in the Days of Noah

 'But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be. '

Matthew 24:37-39

God has given us clue as to what it would look like when the end is coming. 

Humans would be doing all kinds of evil and living a godless lives.

'Then the Lord saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually. ' (Genesis 6:5)

The people back then were doing what their heart desired up to the day of the flood. I would imagine that the boat is humongous and Noah was building it over a long period of time, there was no way that other people did not see what Noah was doing. And I am pretty sure people would asked him what was he doing and Noah would have answered them truthfully. However, the people did not believe Noah and continued with their godless lifestyle. 

For people who have put their trust in Jesus, would have received the knowledge of the end times. We have been taught what has to happen before Jesus second coming, we also have been taught what we must do to stay firm and faithful. Most importantly, like Noah, we have been given assurance that God is faithful and sovereign, and what God has said, will come true. We are not left in the dark by God. He has revealed to us the signs and has given us the Bible. The Bible is so precious because it contains the very words that our invisible God has spoken to the humankind. 

In conclusion, while we do not know the exact hour, but we know that the end will surely come. Like Noah, let us faithfully and courageously continue to "build our boat until it finished" no matter what others say to us.
