It's God's promise 2!

Acts 1:

9 And when He (Jesus) had spoken these things, while they beheld, He was taken up; and a cloud received Him out of their sight.
10 And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel;
11 Which also said, You men of Galilee, why stand you gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as you have seen him go into heaven.

Did I read that correctly?  "- as you saw Him go into heaven!  as you saw  Him?" Did they see Him?            He didn't go secretly.  So we'll see Him when He returns.

Is this true?

Can I believe the Bible or can I, should I, believe the Left Behind books which the authors admit are fiction.
