What are these "greater works" that Jesus told us we'd do? We know that we're supposed to be ready for them. When God says, "Do this", we cannot say, "Nobody has ever done that before". Then you be the first one to do it.
We should be looking forward to this. If we're listening to the Holy Spirit and being led by Him, then we'll know when He says, "DO!" If we try to conjure it up with our own thinking and mind, then we probably won't know. It will just fly on by and we'll miss it.
Many Christians are going to miss a lot of things that God is doing in these Endtimes. He won't use them because they won't be ready.
Be listening for the Holy Spirit to speak in our spirit in a deep inner voice ... a still small voice in our quiet times, and when these greater works come up, we should be ready and willing to do them when He tells us.
