More encouraging help from John MacArthur on some basics on raising godly children. You can read the rest of the article here.
"Instruction" (Gk., nouthesia) is literally a "putting in mind" and also includes the connotation of correction. It refers to the type of instruction found in the book of Proverbs, where, as we've seen, a primary focus is on the training and teaching of children. Such training and teaching doesn't have as much to do with factual information as with right attitudes and principles of behavior.
The key to right discipline and instruction of children is its being "of the Lord." Everything parents do for their children is to be of Him--according to the teaching of His Word, by the guidance and power of His Spirit, and to His own glory and honor. The husband is to love his wife dearly, the wife is to respect her husband, and the two are to be sensitive in raising their children in the things of Christ. If you do that, your children will be the blessing, joy, comfort, and consolation that God intended.
