What did you mean in your MP-3 study of Gospel of Mark when you said: “They are on the right side of Easter, but on the wrong side of Pentecost” in reference to Christians who bear no fruit? I thought by definition if you have no spirit in you (i.e. on the wrong side of Pentecost), you are not a Christian.
What I meant is that while some people are believers, they don’t seem to have any spiritual power. Remember, the disciples received the Holy Spirit on the evening of Resurrection Day, what some call Easter Sunday (John 20:22), but His power was first manifested through them seven weeks later at Pentecost.
Although everyone receives the Holy Spirit at the moment we become believers (Ephes. 1:13-14), there are some who have never experienced His power. In effect, they spend their whole lives stuck between Easter and Pentecost.
