In a way, it's not necessary or prudent to speculate on an actual date for the catching away of the body of Christ, the ensuing tribulation and God's judgement. No man knows the day or the hour (Matt 24:36).
The reason being that at any moment, you could experience your very own 'end of days' - just like that! Unexpected, out of the blue, with no warning and no way to avoid it.
Then where will you be? That's really up to you isn't it.
FACT: There is something after physical death. There is a reality called heaven and a reality called hell. They are both eternal and permanent. Everyone, without exception (that means you and me), will go to one place or the other, regardless of their religious, atheistic, scientific, sceptical or mocking attitudes or beliefs.
The way to heaven, the ONLY way to heaven, is through Jesus Christ. Reject Him and His free gift and there is only one other alternative.
Put bluntly, if you miss heaven, you can't blame anyone else, it's all on you. You chose to reject Jesus Christ, He didn't reject you.
Jesus Christ is God. Come in the flesh as His own sacrifice for the sins of all those who choose to come to Him with a humble, repentant heart. God cannot lie. He has promised to save all those who come to Him.
It's called being 'saved' for a reason. Something to think on today, if you're still alive that is.
