The Mustard Seeds, Aletheia Adventure Series by Eunice Wilkie and published by Ritchie Christian Media.
The fourth book in the Aletheia Adventure Series introduces the reader to Fretters, Meddlers and Mustardseeds. The purpose of the book is to show the reader how necessary it is to have faith in God, even faith the size of a mustard seed. Aletheia was under attack from the Meddlers. What plan should be adopted to defeat the enemy who were causing havoc? Jack came to realise that the mustard seed is tiny, it is nothing at all, but God is greater than all. It does not matter how small or significant you are, if you place all of your confidence in God, you can do great things, even conquer the foes of Aletheia!
