Faithful biblical parenting is demanding, but it is not terribly complicated. It has to do with being a Godward helpful influence through modeling, yes, but in a large way also through conversation. We see this in some of the Scripture's earliest descriptions of the way believing parents are to operate, such as in the early chapters of Deuteronomy where we are told to take every opportunity to be in conversation with our children. We see it in the Proverbs, many of which are presented as a father speaking with his son (beginning with 1:8 and continuing from there). The Apostle Paul uses this format to instruct and counsel his "son in the faith," young Timothy (Cf 1 Ti 1:18 & 2 Ti 2:1, etc). This is the model -- a Godward parent in helpful verbal communication with his or her children.
Only take heed to yourself, and diligently keep yourself, lest you forget the things your eyes have seen, and lest they depart from your heart all the days of your life. And teach them to your children and your grandchildren, especially concerning the day you stood before the LORD your God in Horeb, when the LORD said to me, "Gather the people to Me, and I will let them hear My words, that they may learn to fear me all the days they live on the earth, and that they may teach their children."
