Correct - to some extent.<quoted text>
Not entirely true and woefully incomplete.
Please tell me how it is "woefully incomplete".
While you are posting that response, please be sure to include how another person's life has bearing on you. And I am not talking about your children, spouse, or another family member who is loved.
I'm referring to so-called "Christians" who think that they know what is best for another person or stranger.
