When people hear the word catechism it sounds either scary or old, but simply put a catechism is simply a set of questions and answers that teach you something. People catechize each other regarding their favorite sports teams, bands, and even coffees. A catechism is very effective when it comes to learning about basic principles of the Christian faith.
I wanted to let you know about a valuable resource available at a special price on Amazon today that I think would be especially helpful in discipling your children. It's called The New City Catechism for Kids and it's available today for $1.99, which is a great deal.
My daughter is almost two and we are already beginning to start asking her some of these basic questions. As a simple example, we are asking her, "Who Made You?" and the answer is simply "God".
Your child may not even be able to fully understand these things, but the hope is that when they are old enough, they will already have a strong foundation of knowledge regarding the Christian faith. We pray God will use this knowledge to soften their hearts and help them see the treasure that is only found in the gospel.
I would encourage you to pick up this valuable resource at this low price while it's available today.
