So Many Different Churches

There are many different churches; but how can that be?
When there is only one Holy Bible for all to read
There is one church over here and one over there
And they all profess to be THE house of prayer

There are many different churches; but how can that be?
When we need to worship with love and in harmony
But man wants to separate  his church from the rest
And goes around boasting that his is the very best

There are many different churches; but how can that be?
When a church isn't a church, please take heed
The church you attend just might be another house
With all the people inside and the Lord on the out
