The pre-tribulation rapture is not a new doctrine that began in the 1800s by J.N. Darby. It has been around much longer with very specific details in regard to what happens after (Antichrist, Tribulation etc).
Hopefully the Lord calls today. If not tomorrow the day after… if not the day after… as soon as possible. Anytime. That means our family, the Church, is complete and the soon end of wickedness on the Earth is at hand. Come quickly, Lord Jesus.
