One of the reason I created the Bible verses cards was to help parents introduce the Bible to them. When they hear stories or see colours and images, children become curious and that is when they open their hearts.
The Jesus series is perfect to start with when you want to introduce Jesus to your children. Start by reading the verse and talk about the amazing stories of Jesus. Look for the opportunity to open the big book so they can get used to that.
Start slow and pray for wisdom!
