Herein is the summary of the plan of salvation, attached to the Biblical interpretation of the Revelation, premillenialism:

Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. And whither I go ye know, and the way ye know. John 14:1-4

Spiritualizing things away, or not allowing the Bible alone to interpret itself, which is what futurism, preterism, amillenialism, dominionism, dispentationalism, and every other -ism does, is denying the plan of salvation.

The Lord of hosts hath sworn, saying, Surely as I have thought, so shall it come to pass; and as I have purposed, so shall it stand: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. For I am the Lord: I will speak, and the word that I shall speak shall come to pass; it shall be no more prolonged: for in your days, O rebellious house, will I say the word, and will perform it, saith the Lord God. For this shall the earth mourn, and the heavens above be black; because I have spoken it, I have purposed it, and will not repent, neither will I turn back from it. Isaiah 14:24;55:11, Ezekiel 12:25, Jeremiah 4:28

If not an interpretation of the Bible as it stands, as premillenialism does, then what is the point of being told to watch?

Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: So likewise ye, when ye shall see all these things, know that it is near, even at the doors. Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man. Matthew 24:32-33, Luke 21:36

Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation. For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: Whereby the world that then was, being overflowed with water, perished: But as the days of Noah were, so shall also the coming of the Son of man be. For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be. Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. 2 Peter 3:3-6, Matthew 24:37-39, Luke 17:28, 2 Timothy 3:2-4, Luke 17:29

And if not watching, then who would receive the blessings?

Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. But and if that evil servant shall say in his heart, My lord delayeth his coming; And shall begin to smite his fellowservants, and to eat and drink with the drunken; The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober. Luke 12:37, Matthew 24:48-50, 1 Thessalonians 5:3-6

Spiritualizing away the gospel message, the message of good news, is denying the second advent of Jesus Christ, which too is the premillenialist teaching, which is the teaching of the Bible:

Men of Galilee, why do you stand gazing up into the heaven? This same Jesus who is taken up from you into Heaven, will come in the way you have seen Him going into Heaven. Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth: And though after my skin worms destroy this body, yet in my flesh shall I see God: Whom I shall see for myself, and mine eyes shall behold, and not another; though my reins be consumed within me. For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself. Acts 1:11, 1 John 3:2, Job 19:25-27, Philippians 3:20-21

And denying the second advent is denying the atonement:

So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation. To the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints. Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing. Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works. Hebrews 9:28, 1 Thessalonians 3:13, 2 Timothy 4:8, Titus 2:13-14

Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory? The sting of death is sin; and the strength of sin is the law. But thanks be to God, which giveth us the victory through our Lord Jesus Christ. 1 Corinthians 15:51-57

Not allowing the Bible to be its own interpreter is denying the Blessed Hope found only in the Bible:

But when the Son of man shall come in his glory, and all the angels with him, then shall he sit on the throne of his glory: Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen. Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming. For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. Matthew 25:31, Revelation 1:7, Matthew 24:26-27, 1 John 2:28, 1 Thessalonians 4:16-17

Denying premillenialism, which is the teaching of the Bible, is denigrating Christ while rejecting the defeat of evil:

I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light. I beheld, and, lo, there was no man, and all the birds of the heavens were fled. For thus hath the Lord said, The whole land shall be desolate; yet will I not make a full end. And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, And the slain of the Lord shall be at that day from one end of the earth even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried; they shall be dung upon the ground. What do ye imagine against the Lord? he will make an utter end: affliction shall not rise up the second time. Jeremiah 4:23,25,27, Revelation 20:1-2, Jeremiah 25:33, Nahum 1:9

Premillenialism comes from a personal and prayerful study of "Thus saith the Lord". Where is the wrong in what has been said, and where is the depression in what is about to be said?

And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. But now thus saith the Lord that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine. For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind. The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the Lord, as the waters cover the sea. They shall not build, and another inhabit; they shall not plant, and another eat: for as the days of a tree are the days of my people, and mine elect shall long enjoy the work of their hands. They shall not labour in vain, nor bring forth for trouble; for they are the seed of the blessed of the Lord, and their offspring with them. For the Lord shall comfort Zion: he will comfort all her waste places; and he will make her wilderness like Eden, and her desert like the garden of the Lord; joy and gladness shall be found therein, thanksgiving, and the voice of melody. And they shall see his face; and his name shall be in their foreheads. For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, so shall your seed and your name remain. And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the Lord. He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus. Revelation 21:1-4, Isaiah 43:1; 65:17; 11:6,9; 65:22-23; 51:3, Revelation 22:4, Isaiah 66:22-23, Revelation 22:20
