This sermon is based on Psalm 133.
Psalm 133 from The Message:
How wonderful, how beautiful,
when brothers and sisters get along!
It’s like costly anointing oil
flowing down head and beard,
Flowing down Aaron’s beard,
flowing down the collar of his priestly robes.
It’s like the dew on Mount Hermon
flowing down the slopes of Zion.
Yes, that’s where God commands the blessing,
ordains eternal life.
