Ephesians chapter 4 verses 15 and 16 talk of the body growing up into the Head which is Christ and how every joint or member supplies. It then goes on to say how this causes the growth of the body and the edifying of itself in love.
You may think that you do not matter, but the Word declares that EVERY member supplies. We need each other. We each have been endowed with gifts that others are in need of. This is how the body is to function; as a team.
It has been said that; “half of being smart is knowing what you’re dumb at.” The point is this, “without your smarts there will be some dumbs that are not covered in my life.” You do matter and you are blessed.
