As a christian

I received a new crystal cross from my mother. It will remind me to keep my heart pure and holy like this crystal cross.  And it will always encourage me to help others, to be a good person. My spiritual birthday is 28, April in this year, I remember my church leader told me that being a Christian means that you are changed on the inside, not controlled from the outside. It means that your heart has been changed by the presence of God. It does not mean that you are required to go to church, required to pay tithes, required to be good, required to do anything in order to stay a Christian. It means you desire to do those things because you've been changed.
