I feel that many mothers focus so much on teaching/raising Christian kids that they neglect their own Christian responsibilities. I'm not saying this because I see the hypocrisy in other women's lives, but that I can see from my own life how easy it is to lose sight of priorities. Our job is first and foremost to get to heaven ourselves. “For what shall it profit a man, if he shall gain the whole world, and lose his own soul?” (Mark 8:36) Or, let me change that to: What does it profit a mother if she shall get her children to heaven, but doesn't make it there herself.
Honestly, chances are if the mother doesn't, the children won't. They will follow her example. That is very sad. Let us put focus on our own spiritual lives first – pray, study and be active in the church – and the children will learn from our example more than from what we say.
