There are some more good verses on parenting and raising children (22:6, 22:15), but let me bring to your attention:
Proverbs 22:12 The eyes of the LORD preserve knowledge, and he overthroweth the words of the transgressor.
In my study Bible, I have the word he circled, and the word overthroweth underlined. It is a reminder to me that it is not my job to correct the words of those who lie. It is the Lord's place, and HE will OVERTHROW them. The Lord has also kept His eyes open and has preserved knowledge. Adam Clarke has this to say about the verse: This providence has been wonderfully manifested in preserving the sacred oracles, and in preserving many ancient authors, which have been of great use to the civil interests of man.
It is amazing how much of our time is given to fight the liars and transgressors, when it is the Lord's responsibility to do those things. Lets just take our responsibility a little more seriously and go into all the world and preach the gospel to every creature.
