God wants our marriages to produce Godly Children.
Malachi 2:15 says:
Has not the LORD made them one? In flesh and spirit they are his. And why one? Because he was seeking godly offspring. So guard yourself in your spirit, and do not break faith with the wife of your youth.
1. Parents must Model Godliness
We often hear parents require their children to behave and speak one way, when they themselves behave and speak another (hypocrisy). Children are not blind, they eventual act out what they see at home. Paul tells his spiritual son Timothy,
Be imitators of me, as I am of Christ. 1 Corinthians 11:1(ESV)
2. Parents need to train child in God’s Word
God’s word is a light to our path. It gives wisdom and Godly direction. It helps us understand that our Identity lies only in God. This truth becomes a solid foundation for our lives. When we know that God really loves us and has a plan for our lives everything changes for the better.
My son, if you accept my words and store up my commands within you, turning your ear to wisdom and applying your heart to understanding, and if you call out for insight and cry aloud for understanding, and if you look for it as for silver and search for it as for hidden treasure, then you will understand the fear of the LORD and find the knowledge of God. For the LORD gives wisdom, and from his mouth come knowledge and understanding. He holds victory in store for the upright, he is a shield to those whose walk is blameless, for he guards the course of the just and protects the way of his faithful ones. Then you will understand what is right and just and fair-every good path. For wisdom will enter your heart, and knowledge will be pleasant to your soul. Discretion will protect you, and understanding will guard you. Wisdom will save you from
the ways of wicked men, from men whose words are perverse, who leave the straight paths to walk in dark ways...
3. Parents must Discipline wisely, never out of anger
Hebrews 12:5-11 says this about God’s discipline:
And you have forgotten that word of encouragement that addresses you as sons: ‘My son, do not make light of the Lord's discipline, and do not lose heart when he rebukes you, because the Lord disciplines those he loves, and he punishes everyone he accepts as a son.’ Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits and live! Our fathers disciplined us for a little while as they thought best,but God disciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on,
however, it produces a harvest of righteousness and peace for those who have been trained by it.
