The heavens “drop” at the presence of God. What does that mean? Drop is the Hebrew word nataph, meaning to ooze, to distill gradually, to fall in drops, to speak by inspiration—in other words, to prophesy.
One of the ways God inspires us is by dropping His word upon us. This usually happens during corporate worship when the presence of God is strong. The word of the Lord falls like rain, and there are usually many in the service who get inspired to speak. Some will be inspired to sing prophetically as God drops a song upon them.
