2 Chronicles 5-7

Twice in this passage God interrupted the prescribed rituals of worship in the newly dedicated temple.
5:14 - the cloud of God's glory kept the priests from continuing their ministry of worship.
7:2 - the dazzling light kept the priests from entering the temple.
Through the guidance of the Law Israel was learning the principles of what God required from those who seek to follow him. Because of his greatness he deserves the best of our attitudes, the finest of our "harvests", and the choice of our time. But I think in these passages God paused in receiving what Israel had done and was doing in order that he could give back to his faithful people. I believe God stopped the planned activities so that all present would know that God was pleased with their efforts.
