All those who put so much believe in the words of the bible, should dare to learn about how the bible came to be, and in what timeframe.
If you still think Marc wrote Marc, Luc wrote Luc, etc... you're in for a surprise.
The accent on the second coming of Christ dates from the
reformation, by mistake you could say. Luther didn't have as much information as we have now, and couldn't always put things in the right proportion, perspective. The church of Rome had already given up the idea of the second coming some 7 centuries earlier. You have to know some history for that. Simplified. In the first centuries AC people thought the end was near (where have I heard this before?) and so Christ would soon come again. Centuries past. Dark ages went from bad to worse. The fall of the Roman empire, but also climate change, bringing hunger and disease. But then things started to get better. Maybe the end was not so near after all?. And the idea of a second coming almost disappeared, just until Luther pick it up again.
The idea of ascension, as we understand it now, is not older than 200 years. You could call it someting new (-age).
The bible is a good book. You can learn much out of it. But you shouldn't study the texts only, but also how they came to be, and how they have been changed over time. That changes everything.
A last remark. Jehova's witnesses, or The Watchtower. They have changed their bible over 4 times in the last century. Ask yourself Why?, How can they do that?, Am I sure my church (whatever what church it is) never have been changing things? (in order to keep people in line for instance) It's much about power over people, you know.
