Analyzing more deeply the verse above that says: As in the days of Noah were, is also now in the coming of JESUS, it means that as in the days that were BEFORE the flood they were eating and drinking, marrying and giving in marriage, and knew not that the door of the Ark WAS SHUT, and the flood came and took them all away; So, also now in the coming of the LORD Jesus, the door is already shut before His coming, as the door of the Ark that God shut it before the flood, many will seek to enter in, and shall not be able, and then many many will perish, and then will be revealed who is in and who is out of the Kingdom of God as JESUS said: Luke 20:v.35-36.
