Let customers speak for us
from 7 reviewsBeautiful books! Informative, and introduces foundational biological concepts while tying them to biblical truths in a clever way
My grandson loved reading them. He had lots of questions!
The verse choices were great. The art was lovely. The quality, superior. I have other alphabet verse cards which are smaller but I prefer this size. I like that they are on heavier paper that won’t bend. Looking forward to sharing them with my grandchildren.
I love how these books connect the Gospel to the wonder of God's creation. I especially loved seeing my kid's eyes light up as they made connections between how they are made and God's design. I can see us enjoying these stories for years to come.
We love how fun and engaging these books are! They're intentional, educational, and theologically rich. Highly recommend!
