Incidentally, if you're looking for some help. I recommend the book Parenting With Love and Logic, by Fay and Cline. It's a great practical help for the nuts and bolts of daily discipline. The details will be different for every one of us. The point I'd like us all to remember, though, is that the call of God for us who are Christian parents, just like the call of God for Timothy as a young minister, and the call of God for all of us in our own Christian lives, is the call to discipline ourselves.
Any nincompoop can become a parent, and many do.
But a Christian parent is called to bring up his or her children well, and that is a different matter altogether. We don't have time to talk about everything related to parenting today by any means. We wouldn't if we did this every Sunday for a year. We do have time though to take two simple points from our passage. The first is this.
