Jesus also said it would be "As in the days of Lot". Lot was wisked away before the destruction of Sodom and Gomorrah. If you read the parable of the Wheat and Tares closely, the tares and wheat are harvested simultaneously. God will send His remnant Army (Joel 2) to gather the harvest AFTER He has raptured them for training and returned them for the harvest.

Just as there are 3 harvest periods in the physical, there will be 3 harvests in the Spirit. The first harvest (Barley) will be the innocent from the earth and the Wise Brides who kept their oil/Holy Spirit. This will be at the beginning. The second harvest will be the Wheat (think, Wise Brides get to harvest and bring the Wedding guests). This will happen at the 6th seal when John saw a multitude that no man could number SUDDENLY appear. Notice they are not given crowns like the Bride at the beginning (which we lay at Jesus' feet). This multitude at the 6th seal are given palm branches...Wheat harvest. The third harvest is of the grapes. To harvest grapes you put them through the "winepress". They will be those who must endure to be harvested at the end.

Hope this helps. This is what God has revealed to me over time. He is merciful. He will not beat up His Bride before He marries her. But we must be WISE! Pray for His Wisdom and discernment in all things!
