The testimony of Jesus is the spirit of prophesy, they are ONE and the same, and inseparable, Jesus testimony is also the "narrow path" unto eternal life, his salvation is open to all men, God desires that everyone should be saved, but he will never force anyone to accept his offer, we are free to choose or reject, but in this context we are not free from the consequences of our choice.
1 Timothy 2:4
Who will have [all men] to be saved, and to come unto the knowledge of the truth.
Ezekiel 18:32
For I have [no pleasure] in the death of him that dies, saith the Lord God: wherefore turn yourselves, and live ye
The eternal lake of fire was created for the devil and his angels
Matthew 25:41
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
The reason why Satan was cast out of heaven was because he accused mankind day and night before God, was jealous that God made man in his own image.
Revelation 12:9-11
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
This is why the devil and his servants have such a hatred for mankind and seek to destroy all souls and why they sacrifice babies and children, the most innocent of Gods creation.
Luke 17:2
It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.
God having knowledge of all things would have known that man would fall, and also know who would accept his salvation and who would not. In times past, God looked the other way,
Acts 17:29-31
Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device. And the times of this ignorance God winked at; but now commands [all men] every where to repent: Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained.
But when Jesus was sent into the world that all changed. All men will have the opportunity of accepting the gospel, there will be no excuses, Jesus preached the Gospel unto the spirits in prison who existed before the flood
1 peter 3:18-22
By which also he went and preached unto the spirits in prison; Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing
Revelation 14:6 [all men] know of the Gospel of Jesus, God will give everyone that opportunity
