Brock talked about what it means to be a mature, new man. You've been bought with a price. You are to steward your body as the Lord owns it. You bless others, etc. He discounted the sacred cow of people only having one gift and they are "limited" for the rest of their lives based upon this belief. You can do whatever God tells you to do. Some people will label themselves as a pastor for the rest of their lives, not knowing God may want them to be a teacher here, prophet here, apostle here. You can do any of them.
