Calling the same ColdFusion component from different templates

In a.cfm I have:

<CFSET VerObj = New cfcomponents.VerFold.Ver_Users()>
<CFSET VerObj.Functiion_1(userid)>

In the next few templates, c.cfm, I need to call a different function within Ver_Users.cfc I can do:

<CFSET VerObj = New cfcomponents.VerFold.Ver_Users()> 
<CFSET VerObj.Function_2(userid)>

If I need to call the same cfc again from yet another template down the road and I keep doing this I think it is very awkward and repetitive? the purpose of using .cfc is so that I can reuse or call the functions by just doing:

 <CFSET VerObj,Function_1()> or calling Function_2

from anywhere without keep instantiating the cfc am I correct? is there any example on how to accomplish This?

Instantiating a component has a very small performance penalty. It is not false to re-instantiate it in different templates.

If you really want to cut away these few nanoseconds an bytes of memory you can instantiate the component one time at the onApplicationStart() event im your Application.cfc and store it in the application scope.

<cfset application.verUser = new cfcomponents.VerFold.Ver_Users()>

And then call the functions in your cfm like:

<cfset application.verUser.Function_1()>

@Rbt - you could create an Application.cfc that instantiates the Ver_Users component, and call application.Function1() and application.Function2() in your cfm files. You could create a session and use Session scope, or use Application scope which would treat it as a global, depending on how you want to use it.
