Carnal Christians?

I recently had to close my account from FaceBook due to very sad happenings. I had added people on my freinds list who were freinds of freinds of my freinds. They listed themselves as Christians. Unfortuntly the fruit that they showed on FB was so terrible that it shocked me. None of these people read God's Precious Word. One of them posted they wanted to marry a Leo astrology person. God hatessssss astrology. Astrology is having no faith that Jesus in in control of your life if you say you love him. To depend on astrology is to depend on things of the devil and satan will NOT lead you to a good life.
I was helping a good Deaf person in the ways of God as he recently turned back to Jesus. He got a ASL Deaf Bible and loved it. He lives alone isolated in his town. I was thrilled to be able to help him in the ways of God daily. I love watching God prove His Love to Him. Then these so called Christians started adding mean and rude comment to my comments of trying to help him. One even went so far to say I should not use God or His verses to help this man. It looked horrible to my other Brothers & Sisters and those who may be interested in following Jesus. I saw that more damage than good was being done by me being on FaceBook. I have that beautiful in Christ Deaf man's email address and decided to use that to continue working with him. This whole episode really broke my heart. These so called Christians are so miserable with their own lives. They can't sleep good, have physical sickness that are related to stress. It is no wonder or surprise to see that. Jesus said if you are lukewarm He will spew them out of His Mouth. We can not go on just carrying the Christian word like a badge that we wear on the outside but are nothing like Christ on the inside. We can not mock or fool God with our life and not loving Him with all our hearts, soul and mind. It must be ALL, not 99% but ALL, 100%. God bless!
