Often we find a large amount of criticism of positions without offering a solution. To criticize other positions or other solutions is easy in comparison to expressing opinions or solutions.
In general it is best if we wish to criticize a position if we can offer a better position in it's place. We often find criticisms of positions which offer nothing which is better. It is often as if we are told what ten wrong positions are but have no right position.
The reality is that positively expressing positions is far harder than criticizing. It is easier to tear down than to build. As Christians our primary purpose is to build up.
Sometimes tearing down error is necessary to build up. But tearing down should never be an end in itself, only a means to an end.
The church is a community meant to bring God's blessing to the world. We exist to follow the example of our savior who preferred to serve rather than to be served.
