God loves to see his children getting along. As a parent, I can relate to that. When our children were growing up the house was certainly in turmoil when there was strife between them. But when they were happily playing together or working together on some task, there was a palpable sense of peace and joy in the hearts of their parents.
Psalm 133 uses two illustrations to show how beautiful unity of the children is before the Lord. The first is the anointing oil for the priests being poured on Aaron’s head. This was a special oil (Ex 30) that could be used for no other purpose. This oil set the priests apart to be holy before the Lord. As they carried out their holy calling they pleased the Lord and blessed the people. Christians dwelling together in love and unity demonstrates our holy calling as priests to God.
The other simile is the dew of Hermon. There is some question as to how “dew” on Mt. Hermon in the far north “falls” on the mountains of the country below, especially around Jerusalem (Zion). Perhaps this is talking of the clouds of rain that would build up off the Mediterranean over Mt. Hermon then move on and drop their life-giving water on the mountains of Zion. If so, the reference would be that the unity of the brothers is like life-giving water to the people of Israel.
This is what Jesus prayed for in John 17:20-23 for Christians of all ages. His desire is that we be one in him and love one another as he has loved us (John 13:34-35). This will be a blessing to all the church as the dew coming down from Mt. Hermon.
Prayer: Father, help me to be one who loves my brothers and sisters in you and dwells together with them in love and unity. Help us all to demonstrate the unity that you, Father, and Jesus and the Holy Spirit have by the way we live together as the church. Help us to bless you and bless one another.
