Just before destroying Satan’s organization and his power Jehovah God sends his faithful and true witnesses throughout the land to call the attention of the people to the fact that Jehovah is the Almighty God and that his Word is true; and this he does in order to afford the people an opportunity to know him and to take their stand on his side and thus to be in a position to be spared in the great destruction that shall come upon the world at Armageddon. All people must come to know that Jehovah is the Creator of heaven and earth and the Giver of all blessings. This knowledge is essential in order for them to have an opportunity for life everlasting. Jehovah God’s kingdom under Christ is now here, and immediately following Armageddon the restoration of mankind to human perfection will begin and the obedient ones will be brought back to the state of perfection originally enjoyed by the man whom God created perfect.

The Lord declares this good news or gospel must be given to the people immediately preceding the great battle of Armageddon.
His Works. 1934. p. 27
Satan knows that his time is short before the great battle of Armageddon, and hence he is desperately attempting to turn all men into darkness and from God. Never in the history of the world was there a time of greater darkness than now, because there are so many who claim to teach the Bible but who teach exactly contrary thereto.
