Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
Jesus promised that those who believed on Him would perform works like He did, and even greater works than He did. After Christ’s ascension, His words came to pass. The greater works that Jesus spoke of was the world-wide conversion of sinners. When Jesus ascended to heaven, the Holy Spirit was sent to earth. It was through the Spirit’s power that the apostles performed the greater works.
