To Job:
The Number One Rule is to love your children's mother. Never speak against her in the presence of the child, of course, but you also respect her, support her, help her, care for her, show affection towards her, all in ways the child can see and hear.
Number Two Rule in my book is to attend church as a family. Admittedly, when children are small, you will spend more time taking care of the kids than actually hearing and participating in the services. That's okay. You are building the respect for church in the children. One day, they will ask you about "what's going on" and they will be little sponges, soaking up everything you have to say. As they get older, you can tell them what you FEEL, and they will watch YOU participate.
And then one day you will see them participating beside you, and you will be filled with awe.
Peace be with you,
