Names in the Bible, in Jewish culture, had a meaning. Names indicated a person’s nature, and character. Names indicated a person’s place in God’s purposes, in God’s family. There are places in the Bible where God gives someone a new name, because they had changed. The Bible also says when he establishes his forever kingdom, he will give his children a new name, their true name.
God designed people. God designed them to take a place in his family, in his purpose. He makes his family fit together perfectly.
His family is his vehicle to complete his purposes. Each part, each member, has a role. Each part builds each other part; they build, and add to the body. New parts included.
The health of a church is directly proportional to the number who have found their place. Not people being busy, doing chores. Not greeter, teachers, ushers, nursery workers, ushers, etc. Not that doing chores is bad. All organizations have chores to do to maintain smooth functioning. All parts of the body need to have servant hearts to do the chores. And teaching children is certainly not bad. God loves children. And there are people who place and anointing is in teaching two year olds. But, so much of church activity is filling empty slots. And God’s plan involves a priesthood of every member of his body. How many of God’s family have taken up their priesthood?
