Who we are
At Mustard Seeds Books, we believe that the smallest seeds can grow into something truly beautiful. Inspired by the words of Jesus Christ in the Gospel of Matthew—that faith as small as a mustard seed can grow into something great—our mission is to plant seeds of faith, curiosity, and learning in the hearts of children.
Mustard Seeds Books was created to support families who want to nurture both the mind and the spirit of their children. Our books are designed to make learning joyful while helping young readers grow in character, kindness, and faith.
We publish engaging and meaningful books for young children, including:
📖 Preschool and kindergarten learning workbooks
🎨 Faith-inspired activity and coloring books
🛌 Bedtime storybooks that encourage imagination and values
✝️ Bible-based stories and character-building lessons
Each book is thoughtfully created to help children develop essential early learning skills while also encouraging a love for God, family, and others.
Our goal is simple:
to create books that help children learn, grow, and discover the beauty of faith, one book at a time.
Like a mustard seed planted in good soil, we believe that the lessons children learn early in life can grow into strong roots that guide them for years to come.
Whether you're a parent, grandparent, homeschooler, or educator, we’re honored to be part of your child’s learning journey.
Planting truth and growing disciples — one book at a time. 🌱📚

About the Founder
Marcella Massa Gastrich
FounderHello! My name is Marcella Gastrich, and I am the messenger behind Mustard Seeds Books.
I created Mustard Seeds Books with a simple mission: to plant small seeds of faith, curiosity, and learning in the lives of young children. I believe the early years are incredibly important, not only for developing essential skills like reading, writing, and problem-solving, but also for nurturing character, kindness, and a love for God.
A big part of what inspired this journey is my daughter, Hannah. After recently becoming a mother, I felt a deep desire to share my faith with her and to talk to her about Jesus every day. That desire grew into a vision of creating books that help other families introduce faith, learning, and meaningful conversations into their children’s lives from an early age.
With background design, I have always loved drawing and creating. Combining my passion for design with my love for faith and children’s learning felt like a natural path. Through my books, I hope to create beautiful, engaging experiences that inspire children to explore, learn, and grow.
The name Mustard Seeds Books reflects something very close to my heart: the belief that even the smallest beginnings can grow into something beautiful and strong. Just like a tiny seed grows into a great tree, the lessons children learn early in life can shape who they become.
When I create books, I imagine children laughing, discovering new ideas, and sharing special learning moments with their families. It is a privilege to be a small part of that journey.
Thank you for being here and for allowing Mustard Seeds Books to be part of your child’s learning and faith journey.
