Those involved in relief and development ministries must become ambassadors who preach, teach, take others to give testimonials, taking others to the inner city, mission field, etc. to observe. Educate about funding. Set time limit on funds given to a project. Then slowly decrease funds and stick to it. Raise up new people with new mind-sets.
Missionaries are the primary people to educate.
First educate missionaries, then let them educate the church. The greatest untapped resource in the church are our businessmen. Many times they can accomplish with a few phone calls what we have no idea of how to do. Look at an entire generation as our time-frame for educating. Provide more apprenticeships, internships, short courses with hands-on training.
