• Spend time with your teen even if they are difficult to be around
• Love them according to their love language (see The Five Love Languages of Teens) 
• Make very clear rules and follow through on them
• Create fair consequences when they break those rules
• Let your yes be yes and your no be no. If you feel uncomfortable with something they want to do, say no and stick to it
• Check-up on where they are and what they are doing
• Do random drug testing if you suspect that he/she may be using 
• Be involved in their studies and sports
• Make dinner and sit down as a family
• Say something positive every day. Compliment the way she looks, the way he did his chore, the color of her eyes with the shirt she is wearing. Find something positive to say 
• Don't nag, but clearly state what they are suppose to do and when he disobeys give a reasonable consequence
• Catch her doing something right 
• Pray for your child to know Jesus, to accept Him into his/her life, and to follow Him
• Teach from the word of God. The Bible is our moral compass to live by
• Show compassion for what your teen is going through, be empathetic 
• Be a good role model. Your children are watching you.
• Stop focusing on your happiness and start focusing on your responsibility as a parent to protect your children and raise them into responsible young adults. Your happiness can come after raising your children. You will be happy when your child is well-balanced, feels loved, making good choices, and contributing to society.

Understand the pressures our teens face today. Your teen needs you to do battle for them. Love him, pray for him, guide him, and spend time with your teen. There is resurrection power in Jesus. He will strengthen, guide, and empower you to love the unlovable. It's your job. Discover his or her love language and start filling her love tank. Do the battle. Your child's life depends on it.
