Also,,, I do not consider my Christianity my religion. I am a Christ follower and He is who I look up to for help in my times of need and praise for all He has done for me.
I only worship one God and that is God the Father. The same God who sent His Son to this earth to die on the cross for my and your sins and then rose again after 3 days.
Other than that-- I absolutely agree with you that worship does not only happen (nor should it only happen) inside those 4 walls.
