My hubby believes he is meant to be a preacher. We cannot afford schooling right now besides he does not have the time. I want to support him and help him but what can I do? He knows his Bible very well and has lots of study bibles. He is very knowledgeable and can easily detect false teachings. He is good at researching things. Are there some books or courses that he can get so he can just study on his own? Preferably something that can count towards a degree.
