1 Corinthians 12:15-20 NIV
 Now if the foot should say, “Because I am not a hand, I do not belong to the body,” it would not for that reason stop being part of the body.  And if the ear should say, “Because I am not an eye, I do not belong to the body,” it would not for that reason stop being part of the body.  If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be?  But in fact God has placed the parts in the body, every one of them, just as he wanted them to be.  If they were all one part, where would the body be?  As it is, there are many parts, but one body.
It’s kind of important to know your source. Just because something is said, doesn’t make it so. Especially with as much access to information as there is, things are coming at us from a great many sources that are made to appear legitimate. Truth and reality really do exist, though, no matter what might be said to the contrary. The world is round, God created male and female, life begins at conception, 2 + 2 = 4, there is a heaven/hell, etc. Saying something else doesn’t change reality, no matter who says it for any reason.
There is a reality regarding those who have received Christ. They have been placed in His body as a very special and integral part. That they are not what someone else is doesn’t establish that they are separate from the body. Rather, it solidifies that they are indeed a wonderfullly unique and needed part. Saying that they don’t matter, are not needed, or are not really a part doesn’t change this reality in the least. All it does is detract from developing and becoming the blessing and supply they were designed to be. To be born again is to be a part of Christ’s body like no other. For no reason, especially just saying it, will anything change this reality. 2 + 2 will just continue equalling 4 no matter what is said to the contrary. Might as well just say the truth and be enabled to live it.
