For wheretwoorthree are gathered together in My name, I am there in the midst of them."
Though this statement is true, it is, also, true that God is there when you stand alone. Do not allow people to use this verse to place blame or conviction (when they use this verse on 'face value'). In reality, God is present everywhere. Despite popular belief, God is even present in Hell. He is present everywhere sin is present. Jesus came for the unbelievers not the believers.
Just think, the church is to be seen as a hospital. So, sickness(sin) is present. I feel that The Word, itself, is to be seen, also, as a training manual. I feel that many people, of today, spend all of their lives in the hospital and never receive fisherman training. (Similar to 'life-long' students.) Like most professions, there exists malpractice possibilities. The only difference is that The Word teaches you that though malpractice is unavoidable, don't quit your profession. Unlearn.
