Many years ago, I wrote individual Bible studies and church curriculum for my own children and for the children in our small congregation. I have never charged for these studies. Freely they were given to me, freely I will send them on. For a time, these studies were hosted on a site that claimed to be free. However, the site soon charged those seeking and I withdrew them.
Some have been uploaded to Amazon and are available for $.99. Please, check Amazon as there are more listed there than are shown here. If you would like me to send you a free, reproducible .pdf file, please email me at firstname.lastname@example.org and I would be happy to do so.
