I guess I should have also said that amils and postmils do not see the "thousand years" as a literal 365,000 day span of time. They see it as a symbol, just like all the other symbols in the book of Revelation.
There is no doubt believing the gospel does nothing but good. However, I don't believe Christianity as a whole is growing as fast as Islam.
Your timeframe could be too limited.
I don't believe the millennial kingdom has occurred so I guess that makes me a premillenialist.
There are some postmils who do not believe we are in the "thousand years" yet, but nevertheless believe it precedes the second coming.
Yes, as 1000 years are as one day to the Lord, so we are now and yet in the Day of Salvation.
