4 Peter began and explained everything to them precisely as it had happened:
Sometimes you need to give all the details. Like when you are giving a police report. They want to know everything you remember. Who knows what small detail might be important as the investigation continues. That is one of the key elements of a murder mystery. The little clues given in the narrative that, if strung together, solve the mystery are the ones that are often missed. They get overlooked. Peter doesn’t want to leave out anything that is important as he shares the miracle of his recent trip. For him it is important that the other Jews understand that this was God’s mission and not his. He stays focused on those elements of the story that will help his fellow Jewish believers understand the expansion of the mission field to include non-Jews. This expansion was clearly God’s doing. It had always been so. There was always provision for non-Jews to be included in God’s household. Peter just became an instrument of reinforcement. The Jews had the mindset of “we four and no more.” They were satisfied with the few who had received the message. But God had other plans. He wanted to throw the door wide open and he used Peter to accomplish the first step. God used Peter, the ultimate insider, to start this outreach to the non-Jews. He did this to ensure acceptance by those who might doubt the authenticity of the movement. This was not some fringe person, but the pillar of the Apostles. Some churches today are satisfied with the people they have inside the walls. In fact, if someone tries to enter their small group, they are not welcomed, and often treated poorly. There is no evangelism in these churches, just comfortable back-patting. Peter is an example of the kinds of things God wants to do with many of us. There are those who are rejected that God wants to reach. Are you willing to step outside the comfortable and be used by God? Peter was not comfortable going into a non-Jewish home, and yet he did. Are you willing?
