"And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful. And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely. He that overcometh shall inherit all things; and I will be his God, and he shall be my son. But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." (Revelation 21:5-8)
As Daniel saw the Almighty seated upon His throne, even so He appears here. God's will is irreversible. Satan and his world fight tenaciously against God; yet, "vanity of vanities ... all is vanity (Ecclesiastes 12:8)." The statement, "It is done" contains an overwhelming quality of irreversibility. That which has been decided cannot be reversed, and men will forever feel its impact. God is not intimidated by man's faithless, perverse nature.
The Holy Spirit speaks emphatically when He says in the Greek text, "I, to the one who is thirsting, I will give... ." God Himself through the Person of Jesus the Son satisfies the thirst of the one who willingly comes to the fountain of life. Everyone is thirsty, but not everyone knows it; and neither will everyone come. Yet, to God's glory, there are many who humble themselves and come in the fear of God to drink of Christ's life-giving water. The Lord calls these people overcomers. They are not flawless individuals who have reached some zenith of self-righteousness. They are simply sinners saved by grace whose works reflect a change of authority. They have confessed with the mouth that Jesus is Lord, and they have believed in the heart that God has raised Him from the dead (Romans 10:9-10).
For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God (I John 5:4-5)?
On the King's left hand are seen standing the goats (Matthew 25:33). These are they who have rejected the righteousness of Christ in favor of something else. Some motivated by fear, some persuaded by faithlessness, some corrupted by evil and all blinded by pride, they stand guilty before God. The confessions of their actions disclose the object of their authority. The spotless Lamb was not their hope; therefore, the lake of fire will be their end.
