You can reject the prayer, the Bible study, any spiritual or ecclesiastical message, and learn how to go get a job, or quit drugs and kick alcohol. You can take all the secular aspects of it, reject all the spiritual, and the faith-based people will still love you. But now the time has come when the essence of the Gospel is the reason for the success rates of these groups, and they need to proclaim that success. No one has success like Teen Challenge and Victory Outreach. Speaking from history, they seemed to have been effective without it.
Money is the mother's milk to any kind of work.
It is a necessity of life and comes by the sweat of one's work. There should be rewards for those who do good for humanitarian need. No, you don't have to attend a church, but they do have prayer meetings, bible studies, worship and praise and healing services within the structure of the humanitarian service program center. But you can let it go in one ear and out the other. That's your right.
