Before Jesus ascended to the Father he commissioned his disciples to preach the gospel, saying, “Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved: but he that believeth not shall be damned. And these signs shall follow them that believe: In my name shall they cast out devils; they shall speak with new tongues; they shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.” Mark 16:15-18. Jesus was the “light of the world,” because he had power over sin and disease. The church becomes a light in the world in proportion to her power and purity, and when she reaches the zenith of her power the same power is exercised by her as by the Lord himself. After commissioning the disciples to preach, Jesus was “received up into heaven, and sat on the right hand of God. And they went forth, and preached everywhere, the Lord working with them, and confirming the word with signs following.” Mark 16:19, 20. Although Jesus had ascended to heaven, yet it is said that he was working with them as they preached the word. Here was the secret of their power, “workers together with God.” Again Jesus said, “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.” Mat. 28:19, 20. The Lord here gives promise to be with them unto the end. Although he ascended, yet he says, “I will not leave you comfortless: I will come to you.” John 14:18. The Holy Spirit on the day of Pentecost came and dwelt in the midst of God’s church in the same authoritative power over sin and demons that Christ exercised before his passion. He now comes in the power of the Holy Spirit, performing great deeds of wonder through his church. The church only was visible, therefore became the light of the world. After Pentecost the disciples did as Jesus commanded. They began to preach the gospel, and Jesus working with them, many souls were saved. Peter and John on one occasion “went up together into the temple at the hour of prayer, being the ninth hour. And a certain man lame from his mother’s womb was carried, whom they laid daily at the gate of the temple which is called Beautiful, to ask alms of them that entered into the temple; who seeing Peter and John about to go into the temple asked an alms. And Peter, fastening his eyes on him with John, said, Look on us. And he gave heed unto them, expecting to receive something of them. Then Peter said, Silver and gold have I none; but such as I have give I thee: in the name of Jesus Christ of Nazareth rise up and walk. And he took him by the right hand, and lifted him up; and immediately his feet and ankle bones received strength. And he leaping up stood, and walked, and entered with them into the
