The following post is what prompted me to start and is what encourages me to continue:
[W]hat kind of impact might you have on your children if you did this? Most of us are not remarkable and won’t do anything awesome. But God has made us fathers, and our calling to this role is irreplaceable. As you pray for your children, write it down for them. As you are blown away by the message of Colossians, write it down for them. As you see more of Jesus in the Psalms, write it down for them. And then one day, give it to them.
