That's a question all believers face at some point, and it comes in many forms...

 "What Do You Have? If the only thing you have is a broken heart, you offer a broken heart. So in a time of grief, the recognition that this is material for sacrifice has been a great strength for me. Realizing that nothing I have, nothing I am will be refused on the part of Christ, I simply give it to him as the little boy gave Jesus his five loaves and two fishes—with the same feeling as the disciples when they said, “What good is that for such a crowd?” The point is, the use He makes of it is His blessing." – Elisabeth Elliot

Many times in the body of Christ, there is division. This was not always so and this is not how God intended it to be. 1 Corinthians 12 goes into great detail discussing the body.
