I Cor. 12:12 The human body has many parts, but the many parts make up only one body. So it is with the body of Christ.
If you are a child of God, you are a part of His body. It doesn't matter what you or others may think about it, you belong. You are worthy to be called a child of God and a part of His body because of the work of Christ on your behalf at Calvary. Don't ever for one moment allow anyone to tell you otherwise. You may not be treated as if you were a part of the body, but you are. You may not see yourself connected, but you are. You belong and are an essential part of the body. Therefore, you need to live like it.
Every body part has a useful function. God makes nobody who does not have a purpose. He knows what we are capable of and needed for. He makes no mistake about whom He places in the work of the kingdom. You have an integral role to play in what God desires to do through you in your world. If you don't know what that role is, ask Him right now to show you. He wants you to get busy doing what you are created to do. You will never find contentment in Christ until you do. You will never know the joy and peace of Christ until you are fulfilling His will for your life.
There is no pecking order in the body. Every body part is equally essential for the health and wholeness of the body. Remove any part of the body and the body is incomplete. The body may be able to function, but never quite as well.
The church needs what you have to offer her. She needs your gifts. She needs your heart of love. There is a place for you to serve in her and if you don't, she will never be quite as healthy as she could be. What are you doing for Christ through His church?
Be the very best you can be at what you do for the glory and honor of Christ in and through His church.
