The Institute for Faith, Work and Economics (http://tifwe.org/) based in Virginia, USA, educates and inspires Christians to live out a Biblical theology that integrates faith, work, and economics. That would naturally include stewardship, generosity, giving and issues related to poverty and wealth. They have various special reports (http://tifwe.org/resources/special-reports/), research articles (http://tifwe.org/resources/research-articles/), white papers (http://tifwe.org/resources/white-papers/), op-eds (http://tifwe.org/resources/op-eds/), books (http://tifwe.org/resources/books/), videos (http://tifwe.org/resources/videos/) and links to other resources (http://tifwe.org/external-resources/) that would be of interest to many Christian leaders.
