Matthew 24:36 "But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only. 37 As were the days of Noah, so will be the coming of the Son of Man. 38 For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, 39 and they were unaware until the flood came and swept them all away, so will be the coming of the Son of Man.
Jesus told us that there is a generation of people that will see all the signs of His coming and know that His coming is near (Matthew 24:33-34). If we make a list of the signs Jesus gave us in Matthew 24:9-31 and determine if they have all taken place, then we will know that Jesus' coming is near, but we won't know the day or hour (Matthew 24:36).
Jesus' true followers will know His coming is near, but the rest of the world will be unaware of Jesus' coming to judge and restore the world until it is to late for them to experience anything but judgment to the Lake of Fire (Revelation 21:8). We know this to be true from the time of Noah. Noah was a preacher of righteousness (2 Peter 2:5) and was warning the people of the coming world wide flood that God would use to judge the sinful people of the world. The people did not listen and carried on with their lives as if nothing was going to happen. They were eating and drinking, marrying and giving in marriage while lawlessness (wickedness) increased (Matthew 24:28; Genesis 6:5-7). Imagine the shock of the people when they found that Noah was right and they were washed away in judgment.
Jesus told us what to expect as His coming draws near so we would not be led astray and alarmed (Matthew 24:4-6). Jesus told us to expect many people to disregard His promise to return to judge the wicked and restore the righteous. Jesus said many people will be totally unaware when He returns. Jesus also instructed us what we are to be and be doing while we wait for His return not knowing the day or hour. In the next days we will look at what we are to be and do while waiting for Jesus to return to judge the world and restore His people and the earth.
