well tetelestai at least you are honest about being cold hearted.
personally i don't think you have even the beginings of a basic understanding of who Jesus is, His nature, or how he would have us live our lives. when you say "i am a christian" i really and honestly have no idea what that means to you.
maybe if i met you personally i would find out that you actually can be a real human sometimes, but in print you come across as extremely cold and cruel. i hope that is not really the way you are all the time.
i pray that your heart opens and that you learn what it is to feel compassion before you die.
"...in those days the love of many will grow cold."
