There is great beauty in reflecting upon musical instruments as types and symbols of the unity brought by the Holy Spirit in the lives of God’s people. When Solomon’s temple was dedicated, 120 priests sounded trumpets as one with the singers to praise and thank God (2 Chronicles 5:12-14). The glory of the Lord came down and filled the temple. In the New Testament, on the day of Pentecost, 120 followers of Christ were in the upper room in one accord. The Holy Spirit descended and filled them with His glory. They then became instruments of righteousness doing the will of God.
