Yes. Now Christ rules through the lives of the believers and rules from Heaven. That’s what we mean when we say the Kingdom of God is here and now. At salvation, the Kingdom of God is born in the hearts of the believers and from that time it grows like a mustard seed; this is the sanctification of the believer. This goes on until our glorification. But in the millennial kingdom, the Kingdom does not grow from a small beginning as Jesus taught. The Millennial kingdom is global. Now, in this Church age, Christ is not ruling in an unbelievers heart, that is, Jesus is not the Lord of an unbelievers life. The impression given by the Bible when it describes Millennial rule of Christ is, the whole world under the Lordship of Christ.
Yes, the Bible says we will have tribulation in this world. But Jesus Himself taught about unparalleled tribulation that is yet to come. Also the way Bible describes it, it looks like one of global nature. It does not look like sporadic, instances of persecution that have happened throughout the Church age. The second sign given by Jesus in the Olivet Discourse, seems to describe it as ONE EVENT in the future. Does not seem to be instances of persecution – (Titus, Nero, Hitler etc.).
Yes, the death and resurrection of Jesus broke the dominion of the devil. Through the Holy Spirit God has enabled every believer to overcome the devil. That’s the way a believer can live a sanctified life even now in this fallen world. But I am unable to think of Satan bound now. If Satan is bound he cannot be free or active. Then why does the Bible say that the devil walks about like a roaring lion, seeking whom he may devour. “ (1 Pet 5:8). We ( believers) have the power to bind the devil but still every minute we have to be watchful lest we fall.
That’s why I am unable to subscribe to Amillennialism.
