When the Day of Pentecost had fully come, they were all with one accord in one place.--Acts 2:1
The inhabitants of the world have largely given themselves into Satan's control. He acts as the god of earth. Human beings, wholly given over to evil, cooperate with him in his conspiracies, helping him to carry out his plans against the government of God....
Among the people of God there is to be no dissension, no controversy, and no warfare against one another. The forces of righteousness are to be a unit in their conflict with evil. All the strength of God's people is to be directed against the forces of the enemy. The will of every child of God is to be placed on the side of God's will. Satan's strong efforts against good, the terrible hatred of his agencies against God's agencies, show the need of union and harmony among the forces of righteousness.
A terrible contest is before us. We are nearing the battle of the great day of God Almighty. That which has been held in control is to be let loose. The angel of mercy is folding its wings, preparing to step down from the golden throne and leave the world to the control of Satan, the king they have chosen, a murderer and a destroyer from the beginning.
The principalities and powers of earth are in bitter revolt against the God of heaven. They are filled with hatred against all who serve Him, and soon, very soon, is to be fought the last great battle between good and evil. The earth is to be the battlefield--the scene of the final contest and the final victory. Here, where for so long Satan has led men against God, rebellion is to be forever suppressed...
God's people are to bear a bold, decided testimony for the truth, unfolding the purposes of God by the witness of pen and voice. In place after place they are to proclaim the message of God's Word, arousing men and women to comprehend the truth. (Letter 153, October 26, 1901)
REFLECTION: Putting away all differences, all desire for the supremacy, [the disciples] came close together in Christian fellowship. They drew nearer and nearer to God, and as they did this they realized what a privilege had been theirs in being permitted to associate so closely with Christ. Sadness filled their hearts as they thought of how many times they had grieved Him by their slowness of comprehension, their failure to understand the lessons that, for their good, He was trying to teach them. (The Acts of the Apostles, 36-37)
