THE SCRIPTURAL PHRASE, "NOW IS", MEANS AT 'THIS PRESENT TIME'........

The Scriptural phrase, " now is ", means at 'this present time'. It does not mean 'before now' , and it does not mean 'after now' ,  but it means 'right  now' at 'this present  time'. Keep that fact in mind while reading the following Scriptures which link the day of Salvation , ie. the resurrection  / rapture,  to the presence of Satan in heaven, or lack thereof  :

Luke 10:18 ( Jesus speaking )

"I  beheld Satan,  as lightning, FALL FROM HEAVEN."

John 12:31-32 ( Jesus speaking )

" NOW IS the judgment of this world; NOW shall the prince of this world ( Satan )  BE CAST OUT, and I , if I be lifted up from the earth ( resurrected from the dead  ) will draw ( resurrect / rapture ) all men unto me."

2 Corinthians 6:2

"For He saith,  I have heard thee in a time accepted , and in THE DAY OF SALVATION have I secured thee.  Behold,  NOW IS the accepted time. Behold,  NOW IS the DAY OF SALVATION."

2 Thessalonians 2:2-3

"That the Day of Christ is at hand ......For THAT DAY ( That Day of Salvation  ) shall not come except there come A FALLING AWAY FIRST ,......"

Revelation 12:10-12

"And I heard a loud voice saying in heaven, NOW IS come Salvation , and strength, and the Kingdom of our God, and the Power of His Christ ; for the accuser of our brethren ( Satan )  IS CAST DOWN "

SO, THERE YOU HAVE IT:

These Scriptures tell us that BEFORE the resurrection / rapture of the Church can happen that Satan must FIRST fall away or otherwise FIRST BE CAST OUT of heaven. 

According to Your Holy Word,  come Lord Jesus !
