1)
You must have a relationship with the Lord! If you don't know the Lord, you have no hope. You have no help. What are you going to do during the tough times? What is your future? You NEED Him!
2) You also need the support of your spouse. You should agree on disciplinary issues ahead of time and in private. Never negotiate these situations, in the middle of the situation, in front of the children. Call a time-out, if necessary, and have a private meeting. Then confront the children.
3) It's not too late to change the way things are. There were several instances when we called a family meeting to say "This is not working. From now on, we're going to do it this way". It's ok to do that. Better late than never. Regroup and move on.
4) Start while your children are young. They are never too young to learn respect, to learn to be obedient, to learn kindness and to learn about the Lord.
5) Respect is a top priority. They are never, ever to speak or act disrespectfully to anyone ever! It's typical to think that brothers and sisters are gonna fuss and fight. You're right. They're not always going to get along. But they can always be respectful. Children should never speak/act disrespectful to their parents. Eye rolling, foot stomping, door slamming...not allowed...ever! And screaming "I hate you!" is a big no-no.
6) Teach them from an early age to have their own relationship with the Lord. Teach them to pray and to read their bible. Teach them to take their broken hearts, their worries and fears to the Lord. Encourage them to listen for the Lord to speak to them. Teach them to be obedient to the Lord. If they get the last one, your job as a parent will be so much easier.
7) Last but definitely not the least. Tell them over and over and over that you love them. On good days and bad days. Leave no room for doubt. Hug freely. Be involved in their lives. Ask questions. Know their friends. Listen to them when they talk to you. Even if they're rehashing the Star Wars trilogy for the hundredth time. If you listen to them when they're little, they'll be more willing to talk to you when they're teens.
There you have it! The foundation for my parenting. I didn't always do it right. I learned most of it along the way. But God is faithful and honors our every effort.
