A few years ago when my son was around 5 and sister 3 he had a talk with her. He had been asking everyone he knew if they were a Christian. It was so important to him that everyone know! He was so excited about his own decision. Anyway, one day he came running in from outside and excitedly shouted, "Mom, (sister) became a Christian!!" I knew he was good at persuading her to do lots of things so I began to talk to her. I didn't feel she fully got it but I wasn't going to discount their excitement or childish belief.
A few weeks ago they were talking in the car about being a christian and my son mentioned how they were both christians. I talked about how he had shared with her before but I didn't know if she fully understood since they had been so young. She said she did understand and she had made that decision. Brother told me that he was not talking about that time but another time more lately. I asked about it and they said it was back in the summer when they talked about it and she made a decision to become a christian. I was floored. We talked about it more and I asked more about when, how etc. I was amazed that something this great took place just between them. It was really sweet. I'm sure we will talk more about this decision but I am so excited for her already starting this journey. Her brother got baptized last summer, and come to think of it, that may have been when this whole conversation could have come up. Well, I look forward to watching them embark on this walk of faith!
