First, present yourself to God (Rom 12:1) and see if God has planted you in this fellowship. If so, discover your gifts and the calling of God in your life.
Second, study to show yourself approved unto God (II Tim 2:15). As you grow in your relationship with God, let Him prepare you for effective service.
Third, commit yourself to the work of Jesus Christ in this fellowship. Get involved as a yielded vessel to do Gods bidding anywhere He directs. So should we say, as Isaiah (6:8) said, Here I am, Send me!
