A Story of Light, Science, and God's Promise
After a summer storm, four brothers step outside and spot something extraordinary in the sky. With the help of their grandfather and a simple garden hose, they begin to discover God's secret recipe for rainbows — a beautiful blend of light, water, and the laws of science written into creation itself.
As questions deepen and curiosity grows, what begins as a backyard experiment becomes something much more. A journey into how the world works, and why it was designed that way.

About Maria
Creator, educator, writer, and the heart behind Growth with Gribby.
If there is one thing you should know about me, it is this: I believe learning, healing, and building a meaningful life are not separate from faith. They are part of it.
God is not distant from our growth. He is present in it. In the questions, in the rebuilding, and even in the messy middle.
My journey did not start in a perfectly organized planner with color-coded goals. It started in real life.
Raising children. Navigating challenges. Healing from hard things. And asking bigger questions about the world, about people, and about God.
I was the child who asked a million questions. Why does this work? How does that happen? What does this mean? That curiosity never left. It simply grew up with me.
Over time, those questions deepened. Not just how things work, but why we are here, how we grow, and how faith and truth come together.
With a background in science and psychology, I've spent years studying how people learn and develop. But the most important lessons didn't come from textbooks. They came from life, from motherhood, and from a growing understanding that truth, beauty, and goodness are never in conflict.
And what I found is this: Real growth often happens in the middle of the mess. And God does some of His best work there.
Everything I create is centered around helping children and families grow in both knowledge and faith in a way that feels natural, engaging, and real. You will find:
My children's books are especially close to my heart. They are written for the kids who ask questions. The ones who notice everything. The ones who want to understand how the world works and where God is in it.
Because curiosity is not separate from faith. It is often where faith begins.
I don't believe in overcomplicating things. I believe in:
I believe God created our minds to explore, our hearts to seek Him, and our lives with purpose. And I believe the next generation deserves tools that help them grow in all of it together.
Whether you are here to teach your children, grow in your faith, or build something meaningful for your family, I'm truly glad you're here.
