Congratulations to you! I appreciate what everyone has said here already. A couple of helpful passages that come to mind:
Deuteronomy 6:4–9
4 “Hear, O Israel: The Lord our God, the Lord is one! 5 You shall love the Lord your God with all your heart, with all your soul, and with all your strength.
6 “And these words which I command you today shall be in your heart. 7 You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. 8 You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. 9 You shall write them on the doorposts of your house and on your gates.
Ephesians 6:4
4 And you, fathers, do not provoke your children to wrath, but bring them up in the training and admonition of the Lord.
Raising children is discipleship. Fathers and mothers are called to this important task of passing down the faith (Ps. 78). In particular, fathers are responsible for the training of their children because they are the head of the home. Us men will be tempted to be slack in this regard due to other things vying for our attention (work, school if applicable, home upkeep, ministry involvement, etc.). Yet, we cannot forsake this very important calling.
As another person pointed out, children will sin. I believe men in particular can struggle with anger but we must remember that the Scriptures clearly inform us that the anger of man will not produce the righteousness of God (James 1:20). Godly fathers want their children to be godly but disciplining in anger will not produce that. Instead, it will produce bitterness and resentment. Above all, we must recognize that we and our wives cannot parent in our own strength. We need the Lord so cry out regularly to him in prayer and ask for wisdom from the Lord who gives liberally (James 1:5-6). Our children need to see us repent of our sin, ask for forgiveness when we sin against them, and model living as disciples of Christ doing all for the glory of God. Then when our children sin, we help them imitate us as we imitate Christ. We point them to the gospel constantly. If we simply have household rules but they are not rooted in God's word and authority it can come across as mere moralism.
One helpful book I am working through, which is an older book and out of print, is Family Man, Family Leader by Philip Lancaster. It has been an encouraging read so far.
