The unity of the body is seen in the diversity of gifts and people - seen especially in v. 25. This unity within diversity is seen most clearly in the trinity itself, and then worked ou in the body of Christ, the Church.
Sometimes when things don't work just the way we think they out to, we head back into wht we know -- our default position. But God has his plan, his time and he will never let you go if you are willing to follow.
