A common misinterpretation is that this verse guarantees believers will perform miracles more powerful than Jesus, such as raising the dead on a grander scale or achieving supernatural feats beyond his, leading to expectations of personal fame through healings or prophecies; instead, the 'greater works' refer to the expansive reach of the church's mission through the Spirit, producing more salvations overall rather than superior individual miracles, which can foster disappointment or false teachings when such expectations go unmet.
John 14:12
King James Version (1769)
12 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 assures his disciples that those who believe in him will perform the same works he has done and even greater ones, not in power or spectacle but in scope and impact, because his departure to the Father enables the sending of the Holy Spirit, empowering believers to spread the gospel worldwide, resulting in multitudes coming to faith far beyond what Jesus accomplished in his localized earthly ministry.
