OUR STORY
Guard Your Heart
Several years ago, God planted the idea in my heart to write children’s books. But I doubted whether I understood it correctly. After all, I was a mother and teacher, not an author.
In trying to find children’s books for my kiddos that taught values through the biblical lens, I was unsuccessful. Then I began to take the idea of writing a series of children’s books more seriously. My husband and I prayed and were fascinated with how the project gradually took shape into an ever-growing endeavor: a topical, hands-on series for children age six and older under the name Guard Your Heart.
At the start, we had no idea how much work was ahead of us. But God put the right people with amazing talents in our path at exactly the right time. To God be the glory for being such an awesome provider! We are infinitely grateful to Him.
Yet, we are still far from the end of this wondrous journey, with a lot of work yet to do. We would like to eventually offer 30 colorful hardcover children’s books, each focused on a Christian value, such as gratitude, honesty, obedience, diligence, and patience.
In writing these books, one idea is particularly important to me. As parents, we try to instill God-pleasing behavior in our children, e.g. not to lie or steal. Maybe our child does it wonderfully, but their heart is far from God. That’s why I chose guarding the heart as the central theme of every book. My hope is that readers understand it is not enough to have good character traits, because a sinful heart is still far from God and needs forgiveness over and over. Only with God’s help can we guard our hearts from sin and become truly happy individuals!
With over 20 years of experience working with children, my inspiration for the stories comes from everyday life situations. All stories are presented in a child-friendly manner and are based on true events in my own childhood or in the lives of my children and friends.
I hope that our books will bring a lot of joy and be a blessing to you and the children you care about!
With Love,
Esther
