Also can we morph the meaning of purpose to not necessarily mean an end "goal", rather a process of change and learning perhaps. I think that the idea of "meaning" and "purpose" comes strapped with so much baggage and projection that it rarely becomes helpful.
Yes it is possible but i am afraid it means end goal and reason we were created in the first place.
Worshipping God for that long is a process, something you do often but it has an end or direction it's working towards which is either hell or heaven.
In the context in which i used the word 'believer', it would be hard to deny that it means an end goal.
