WCOI is a faith-based organization and it depends on donations from fellow believers who are lead by the Lord to give. You can donate money towards an Audio Bible for the Blind/people groups/people with disabilities/children/oral learners, etc. Or you can also donate towards a language recording.
Additionally, if you want to bless our staff you are welcome to do that as well. Please give as the Lord leads. As you may know these audio units are imported into India and are available against a highly subsidized donation at our office, and it is further reduced to a price that people can afford during our distributions.
