John 14.12-14 cont.
12 In all sincerity I tell you: the one believing in Me and the works that I do, he will do even greater things than these, because I am going to the Father.
13 And I will do whatever you should ask in My name, so that the Father may be glorified through the Son.
14 I will do whatever you ask Me in My name.
There are many coaches who train others in a particular sport. Often these trainers have been successful in that sport, be it tennis, snooker, football, or whatever. Their objective is to train others to achieve greater success than they did, and to reach greater heights of success than they did.
Jesus told His disciples that they would do even greater things than He did.
When we stop to consider all that Jesus did, and all that He does for us it seems incredible that we could do anything to the same level as Him, let alone greater than what He did.
What could Jesus have meant by these words?
We are familiar with the stories of how He healed people, delivered people from the bondage of evil spirits, and released people to live a life not dominated by sin. We know that Jesus paid the price of the sins of the whole world for all time. What could be greater than that?
Did Jesus mean that the number of works that we do are greater in number? As the church grew with more and more believers being added to the church, there is greater scope for more of the works of Jesus to be done.
Did Jesus mean that as mankind’s understanding of science, especially medical science increased, there would be greater works done? We can see that through the advancement of medical science operations are carried out today that would not have been dreamt of even a few years ago. These are lifesaving and life changing operations.
However, as much as there is some truth in these explanations they don’t seem to really fit the context.
The early church was used to seeing great acts of the power of the Holy Spirit. In Acts 19.22 we read:
 God gave Paul the power to do unusual miracles,  so that even when handkerchiefs or cloths that had touched his skin were placed on sick people, they were healed of their diseases, and any evil spirits within them came out – (NLT).
Let us take to heart these words of Jesus and live with the expectancy of seeing ourselves being used for the greater works that Jesus talked about.
