The works of Christ testified to the fact that He was sent by the Father (John 5:36) and that the Father was in Him and He was in the Father (John 14:11). But then Jesus makes a really bold statement: whoever believes in Him will do greater works than He has done. How is that possible? What does Jesus mean by this?
This has to be understood in the context of scope of ministry. As our Lord finished His earthly ministry, we only see a few true believers in a small geographical area (about 120 assembled in Jerusalem according to Acts 1). As you move on through the New Testament, and now into modern times as well, you see the growth of the Church. The work of the gospel has gone global reaching hundreds or even thousands of people groups. And it is in the proclamation and application of the gospel to all these people groups and cultures that the Lord can say that it is a “greater work.” The work of the Church to this day is the greater work of reconciliation of sinful men and women to our loving heavenly Father—God has given us “the ministry of reconciliation … entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us” (2 Corinthians 5:18-20).
In case we’re feeling pretty confident right now about what we can do, remember that it is only because Christ has ascended to heaven, mediates the new covenant, and has sent the Holy Spirit to dwell within us that we are able to do these greater things. So let’s be real and humbly work alongside our Father, as co-laborers, praying in Jesus name for His kingdom to come, His will to be done on earth as it is in heaven in anticipation of His return when the work is completed.
