Is there two different stages in the purpose of an action?

Hi,

Could any native right my ideas?

1. If the purpose as an intended aim in the mind, it has several way to show that.

The action has to do something as its purpose.

The action purposes to do something.

The action intended to do something.

For business purpose, he come toLondon. [for]----in regard to ;

For helping us do this, he has commanded us to meet often and partake of the sacrament.

To everyone’s amusement, the actor fell off the stage.

2. If the purpose as a use / effect / result, it has several ways to show that.

For helping us do this he has commanded us to meet often and partake of the sacrament.

To everyone’s amusement the actor fell off the stage.

This computer is not quite as powerful as the other one, but for all practical purpose it is just as good.

(here, the [be good] has its logical power shows an added beneficiary unto [all practical purpose))
