There was a girl in my class who liked to talk about herself. A lot. The stories she told seemed far fetched and braggy, but the other kids didn't seem to mind. The second day, we were waiting to get started. She said that she had never been in a church before. She described how her mother said that she was free to choose her own religion, and she didn't know much about Christianity.
Now I've been a Christian for a good many years, and I can take you down the Roman Road, but God told me to keep silent. So I sat there with my mouth shut. That was difficult. Then one by one, the other teens started to witness to this girl. They told her about Jesus and what He has done. They described their relationships with the Savior. And I just sat in the corner silently rejoicing that teenagers were sharing the Gospel with this girl.
We homeschool moms complain about having to do standardized testing. It's a disruption and a large expense. But because we have this requirement, a 13 year old girl entered a church for the first time and heard about salvation. God can use anything, even standardized testing.
