Just before he left them, Christ gave his disciples the promise, “Ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth.” “Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world.” While these words were upon his lips, he ascended, a cloud of angels received him, and escorted him to the city of God. The disciples returned to Jerusalem, knowing now for a certainty that Jesus was the Son of God. Their faith was unclouded, and they waited, preparing themselves by prayer and by humbling their hearts before God, until the baptism of the Holy Spirit came. PH154 6.1
“And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.” In that assembly there were mockers, who did not recognize the work of the Holy Spirit, and they said, “These men are full of new wine. But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: for these are not drunken, as ye suppose, seeing it is but the third hour of the day. But this is that which was spoken by the prophet Joel.” Read the history. The Lord was at work in his own way; but had there been such a manifestation among us, upon whom the ends of the world are come, would not some have mocked, as on that occasion? Those who did not come under the influence of the Holy Spirit, knew it not. To this class the disciples seemed like drunken men. PH154 6.2
After the outpouring of the Holy Spirit, the disciples, clothed with the divine panoply, went forth as witnesses, to tell the wonderful story of the manger and the cross. They were humble men, but they went forth with the truth. After the death of their Lord, they were a helpless, disappointed, discouraged company,—as sheep without a shepherd; but now they go forth as witnesses for the truth, with no weapons but the word and Spirit of God, to triumph over all opposition. PH154 7.1
Their Saviour had been rejected and condemned, and nailed to the ignominious cross. The Jewish priests and rulers had declared, in scorn, “He saved others; himself he cannot save. If he be the king of Israel, let him now come down from the cross, and we will believe him.” But that cross, that instrument of shame and torture, brought hope and salvation to the world. The believers rallied; their hopelessness and conscious helplessness had left them. They were transformed in character, and united in the bonds of Christian love. Although without wealth, though counted by the world as mere ignorant fishermen, they were made, by the Holy Spirit, witnesses for Christ. Without earthly honor or recognition, they were the heroes of faith. From their lips came words of divine eloquence and power that shook the world. PH154 7.2
The third, fourth and fifth chapters of Acts give an account of their witnessing. Those who had rejected and crucified the Saviour, expected to find his disciples discouraged, crestfallen, and ready to disown their Lord. With amazement they heard the clear, bold testimony given under the power of the Holy Spirit. The words and works of the disciples represented the words and works of their Teacher; and all who heard them, said, They have learned of Jesus, they talk as he talked. “And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.” PH154 8.1
