In the wisdom literature of the Old Testament, the Holy Spirit has provided you with a guide book for understanding emotions. Biblically, emotions can be thought of as the first responders of the heart. If the heart is good and well-guarded emotions can work for us, not against us. If the heart is not guarded then emotions can bring much damage. This is why Solomon is adamant that the heart be guarded above all else (Proverbs 4:23). The book of Job tells us right away the value of emotions. We read that Job feared the Lord and shunned evil. His strong emotional fear of God protected him from evil. This is the same emotional response that protected Joseph when he fled from the arms of Potipha'’s wife. This the type of emotional behavior you want to build into the lives of your children.
Emotional protection doesn't just happen. This is why God wants you to talk about how wonderful and powerful he is 24/7. As Deuteronomy 6 instructs, what you tell your children about God is to flow from your heart to their heart. This transmission of truth from the heart is essential for your child's well being.
