John 14:12 Truly, truly, I say to you, whoever believes in me will also do the works that I do; and greater works than these will he do, because I am going to the Father.
The Lord Jesus made this astounding statement. I have heard so many people who have assumed that meant that, as Jesus' followers, we would do more spectacular things than He did. There have been miraculous healings, people raised from the dead, sicknesses healed, etc. I fully concur that a lot of this has been done in Jesus' name. But can we ever really say that anyone has done more than Jesus in this area? I do not think so.
Yet, when Jesus was crucified everyone abandoned Him except a few women. Then 50 days later there were 120 people. By human church growth standards, Jesus was average, at best. Yet when Peter preached 3000 came to Christ. This is something that we do not see of our Lord Jesus.
It is my belief that the greatest miracle is the regeneration and salvation of a wicked soul. When Jesus spoke of 'greater things' I believe He was referring to the salvation and discipleship of souls. I believe that Jesus was saying, that through His followers He is going to save more people than anyone can possibly imagine (not universalism, put your heresy stake away).
Why do we operate as though Jesus is unwilling to save when this was the reason He came? Why do we assume that it has to take a long time before someone comes to Christ? Why do we preach the gospel and expect no one to come to Christ? Ought we not simply stay home if this is the case? I submit to you these ideas come from our fallible experiences and not from Scripture. I think we are trying to protect our fruitlessness or our faithlessness. Just my thoughts.
