There’s good advice in Scripture for those in authority within our schools:
1 Corinthians 13:4-7 (NIV)
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
Mercy triumphs over judgment.
Romans 12:3 (NIV)
I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment.
