God expects parents to raise their children to serve Him. Parents will answer to God for every child He entrusts to their care.
PROVERBS 22:6 KJV
6 Train up a child in the way he should go, and when he is old he will not depart from it.
There is a vast difference between training and mere teaching. Training involves not only teaching, but also practicing what is taught until it becomes a habit.
Proverbs 22:6 does not say children will depart from the way and return to it when they are old. Instead, it promises they will never depart from the correct way -- if they are properly trained.

One reason God blessed Abraham was because God knew he would raise Godly children. That requires commanding children to do right -- not just making suggestions and allowing children to choose what they think is best.

GENESIS 18:19 KJV
19 "For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him."

First Timothy 3:1-7 lists important qualifications for someone involved in a ministry of church oversight. One of them, in verse 4, has to do with how his children act.

1 TIMOTHY 3:4 KJV

4 One that ruleth well his own house, having his children in subjection with all gravity
It is your responsibility as a parent to train your children to obey your word and show you respect. If you do not -- you will be to blame for destroying your child.
PROVERBS 19:18 KJV

18 Chasten thy son while there is hope, and let not thy soul spare for his crying..

If children do not obey, they must be corrected. It is part of the training process so they will learn to do right. The Bible teaches this should be done by using a rod of correction. We might call it spanking with a paddle.
PROVERBS 22:15 KJV

15 Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.

PROVERBS 23:13-14 KJV

13 Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
14 Thou shalt beat him with the rod, and shalt deliver his soul from hell.

PROVERBS 29:15 KJV

15 The rod and reproof give wisdom: but a child left to himself bringeth his mother to shame. .

Modern ideas on raising children may change every few years -- the Bible never changes. The rod of correction -- correctly and prayerfully used by a loving parent -- will produce emotionally healthy and happy children.
In life there are consequences to wrong-doing which bring pain. Children need to learn this -- that is why we must spank them. Even though we receive forgiveness, many times there are painful consequences to face.
Spanking Guidelines

Spanking children should not be to punish them for their wrong, but to help correct them.
Never spank a child for an innocent mistake or an accident. Spank only in response to a rebellious act of disobedience to a clearly defined and known rule. You should have clear rules for your children.
Parents should say what they mean -- and mean what they say -- without having to raise their voice or constantly threaten their children. If children do not respect their parent's word, it will be difficult for them to respect God's Word.
Never spank a child unless they knew beforehand what was expected of them. Make sure they understand what they did wrong. Children must understand that the spanking is a consequence of their choice to disobey a clear, known rule -- not the result of their parents' anger.
Never spank a child when you are angry and not in complete control of your emotions. Never hit a child with your hand. Never hit a child anywhere except their rear, where the Creator provided extra padding for their protection.
After spanking your child, always hug them, tell them you love them, and pray with them. Train them to ask God to forgive them for the wrong they have done.

EPHESIANS 6:1-4 KJV

1 Children, obey your parents in the Lord: for this is right.
2 "Honour thy father and mother; (which is the first commandment with promise)
3 "That it may be well with thee, and thou mayest live long on the earth.."
4 And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.

God promises that children who honor their parents will live long on the earth, and it will be well with them.
Be Examples

Parents must be good examples for their children, because children are natural imitators.
DEUTERONOMY 6:5-7 KJV

5 "And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
6 "And these words, which I command thee this day, shall be in thine heart;
7 "And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up..

If parents themselves do not live what they teach their children, the children will realize they are hypocrites, and will not follow their teaching.

COLOSSIANS 3:17-21 KJV

17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
18 Wives, submit yourselves unto your own husbands, as it is fit in the Lord.
19Husbands, love your wives, and be not bitter against them.  .
20 Children, obey your parents in all things: for this is well pleasing unto the Lord.
21 Fathers, provoke not your children to anger, lest they be discouraged.

You must put God's Word first and walk in love toward your children to succeed as a parent. Give them time and attention. Do things together. Play with them and talk with them. Showing love to them, and teaching them about God, are essential.
You should not yell at your children or provoke them to wrath. Parent's words are extremely important. Build your children up: encourage them and praise them. Tell them you love them.
If you have fallen short in raising your children up to now -- cry out to God for forgiveness and help. He will forgive you and help you.
As long as your children are still alive, there is hope for God to change them. If you will pray in faith, obey God, and walk in love, God will work in your children's lives and change them

Children are a heritage from the Lord. (Psalm 127) Whether you are a stay-at-home-Mom, a working Mom, a married Mom, or a single Mom, you have been given the most awesome privilege and responsibility ever entrusted to mankind. A little life to guide and teach all of life's wonders.
At times this task can seem overwhelming. There is no training course, no owner's manual, no user's guide which can ever prepare you for everything your child will depend on you to teach them. Well...good news! There is one source for all the answers you will need in raising your children. One expert you can turn to when you don't know the right decision to make. One haven to run to when this job proves too stressful. One friend with whom to share all the joys, pains, accomplishments and failures of parenthood. There's God!
God refers to himself as our Father, assuring us that he understands the complexities of being a parent. He loves us as much as we love our own children, and wants us to succeed as parents. Therefore, it is His pleasure to offer us all the answers to raising Godly children. Our responsibility, then, is to ask Him for His help. To lift our children's needs and our needs as parents to our heavenly Father. Then, to trust Him for the wisdom to raise our children to be all that God intends for them to be.

Pray, then for your children, and when parenthood proves to be a bit overwhelming, run into the arms of your Father for comfort and guidance.
He loves you!
