"A gentle answer turns away wrath, but a harsh word stirs up anger."Not only will angry words not teach my children gentleness, but they also cause my children to be angry.
My goal is to really meditate on the following verses daily, and pray for a spirit of gentleness with my kids.
"The LORD is slow to anger, abounding in love and forgiving sin and rebellion. Yet he does not leave the guilty unpunished; he punishes the children for the sin of the fathers to the third and fourth generation."
"In your anger do not sin; when you are on your beds, search your hearts and be silent. "
"The LORD is compassionate and gracious, slow to anger, abounding in love."
"A fool gives full vent to his anger, but a wise man keeps himself under control."
"Do not be quickly provoked in your spirit, for anger resides in the lap of fools."
