Jesus answered: “Don’t you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, ‘Show us the Father’? Don’t you believe that I am in the Father, and that the Father is in me? The words I say to you I do not speak on my own authority. Rather, it is the Father, living in me, who is doing his work. Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the works themselves. Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father. And I will do whatever you ask in my name, so that the Father may be glorified in the Son. 14 You may ask me for anything in my name, and I will do it. John 14:9-13

If what Jesus said in the previous statement confused his Disciples, what He said after that would be sure to throw them into a whirl!
“If you’ve seen the Son, you’ve seen the Father” and “I am in the father and the Father is in me.” They’re trying to take it all in but he’s not making it easy on them.

What he continued to say must have blown them away. “and [those who believe in Him] will do even greater things than these. How could they do greater things than the man they were to worship?

It’s actually not a bad question even for today. Collectively, as a Church, we can certainly do more things than Jesus did. Even at a low figure of 100 million Believers in the world (and as high as one billion) the combined efforts of us all exceeds what Jesus had done (in terms of quantity). It’s a numbers thing.

It’s apparent, then, what our job is: 1) Love the Lord with our heart, soul, mind and strength, and 2) love our neighbors as ourselves. The greater works will be byproducts of those two activities. Our focus, however, should be on the greater works; it should be on 1 and 2 above.
