Hello Tian (buggy),
I was a premil until I heard two Messianic Jewish friends talking excitedly about the alleged to-be-rebuilt temple in Jerusalem, and the renewed sacrifices; I said to them, "Hey, haven't you guys ever read Hebrews?" I studied the amil position from there, and saw the sanity of it and fidelity to the Biblical data. It took me a while to come to a sound amil view on some particulars, such as the two witnesses in Rev 11 (on this, and an intro to amil exposition, check out G.K. Beale's great sermon (MP3 download),
“Two Witnesses in Revelation” (⇐ link), and also the battle in Zech 14:1-4.
The Bible teaches there are only two ages, this age (or world) and the age to come. There is no third, such as a 1,000 year reign of Christ in Jerusalem before the eternal state,
or a "golden" age of "Christianized" nations (outwardly conforming to the Law) where the severity of the curse will be diminished (increased longevity, predator animals at peace with their prey, etc). No, things will get worse in the world, the judgments of God will increase, and the church will come under greater and greater tribulation (persecution). Do you know that more Christians have died in the last century than in all the centuries
combined since the Lord's resurrection? These fires but purify the precious faith of the saints.
The thousand years of Rev 20 — the famous millennium — is that period from the triumph of Christ over the devil, when He made a spectacle of him through the victory of the cross, till the end of the age. During this period Satan is chained / restrained from deceiving the nations (as he did before the advent of Christ) and marshaling them to attack and annihilate the church. At the end of the age he will be loosed, and will indeed deceive the nations again, and attempt to utterly eradicate the people of God from the earth, at which point the Lord will return to destroy him and vindicate His beloved people. Then the resurrection, the judgment, and the eternal state.
The Lord's "cattle upon a thousand hills" (Ps 50:10) doesn't mean literally a thousand hills, but
the fullness of the world — all the hills — and all its cattle are His, even as the fullness of the entire lifespan of the NT church is signified by "a thousand years".
The Reformed Baptist pastor and teacher, Samuel Waldron, wrote a good book on this:
The End Times Made Simple (⇐ link). You won't go wrong on this with Waldron.
We are living in the Millennial period. And we need to be prepared for those things that shall come to pass.
