True, if you accept a linear progression in Revelation. I believe Revelation is reiterative.1. Satan will be bound; he is not currently bound.
He executes his destructive will, but not outside of the limits that God has set.2. Amil could venture bound (prohibited) from executing his destructive will on the Church, but Satan is not bound and he continues to execute his destructive will on the church right now.
"...we must through much tribulation enter into the kingdom of God."3. How do we account for cruelty and persecutions against the church over the years?
"For verily, when we were with you, we told you before that we should suffer tribulation; even as it came to pass, and ye know"
"For whom the Lord loveth he chasteneth,"
"Wherein ye greatly rejoice, though now for a season, if need be, ye are in heaviness through manifold temptations:That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:"
"And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased. "
"Yea, and all that will live godly in Christ Jesus shall suffer persecution. "
One might understand "nations" as a parallel to "Gentiles", representing the opening of faith to the Gentiles during this age of the new covenant.4. Plus, the text says Satan is bound so that he would not deceive the nations, not the church.
