1) Communicate humbly with your teen.
“The most helpful thing to remember is that your teenager is more like you than unlike you…. There are very few struggles in the life of my teenager that I don’t recognize in my own heart as well…. Come [to the conversation] as a fellow sinner.” Paul David Tripp
For all have sinned and fall short of the glory of God. Romans 3:23
2) Postpone talking if you’re angry.
And the Lord's servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil, correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth, and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will. 2 Timothy 2:24-26
3) Postpone talking if your teen is angry.
“Listen, don’t lecture. You can usually say all you need to say in about 2 minutes and 30 seconds before you start repeating yourself.” Kenneth Maresco
When words are many, transgression is not lacking, but whoever restrains his lips is prudent. Proverbs 10:19
5) Correct only what you must; overlook what you can.
Good sense makes one slow to anger, and it is his glory to overlook an offense. Proverbs 19:11
6) Acknowledge your own sin.
7) Don’t let the conversation end until you have encouraged your teen.
Gracious words are like a honeycomb, sweetness to the soul. Proverbs 16:24
A good word makes him glad. Proverbs 12:25
