The rapture is an event in the future when believers are caught up and carried away in great joy by their Lord at His return. It is called the glorious hope and is the most-looked-forward event in His-story on this earth.

There is no secrecy / invisibility element to this event as is evident from several scriptures to the contrary. "Beware: In case of Rapture this car will be driverless" shows only ignorance of the scriptures. He is not coming secretly for the Church exactly seven years before His glorious coming (which will invariably reveal the exact date of His (second!) coming) – wouldn’t that make it His third coming? He will appear a second time – just one more time. Unto them that look for Him shall He appear the second time without sin unto salvation. – Heb 9:28. The Lord’s coming to the air (first heaven) is nevertheless a coming – certainly He should come out of Heaven’s door! And His coming is not to cause random accidents on the road but to cause eternal destruction. – 2 Thes 1:7-10.

Yes, His coming will be like a thief in the night – but it only tells about the surprise element – the unexpected time – and this, for the unbelievers. Believers will however remain prepared and anticipate His return (Tit 2:13). They should!

And, there is no mention of the saints being with the Lord for a short time (exactly 7 years) in heaven – we will be with Him for ever.
