I wrote to a woman who says she's a Christian and who is ill that I want God to heal her, Satan attacks innocent people, some people think that only sinners are attacked, and they blame others without even knowing them. The reaction I received was that she doubts my sincerity, thinks I need to examine my heart, deleted my words of encouragement, and blocked me from responding.
So, what do you do when you try to heal and people spit in your face and slam and lock the door? You don't retaliate. You just shake the dust from your feet.
And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet. (Matthew 10:14 KJVR)
