If you are truly a child of God and member of his kingdom, then I would encourage you to take seriously the church, the body of Christ. This church takes local expression all over the world in various forms. Find a local expression that is faithful to our head, to Christ. And take your place within his body, seeking to advance the kingdom of God here on earth. Be the body part you were called and equipped to be.
As believers we are members together of one body, the body of Christ. Each of us are equipped by God to serve the body, under the Lordship of Christ. There is no place for boasting, or thinking to highly of yourself because of what God has given you. Nor, is there a place for thinking too little of yourself because your gifting does not seem to compare to some others.
