What was going on here? Samuel tells Saul what is about to take place and explains that he will become a new person.
These prophetic people come down from a hill prophesying and playing music perhaps dancing and Saul gets close to them and zap, he's prophesying too and afterward, he's a new person.
This kind of stuff is happening again and will continue to happen in our meetings. We need people prophesying and being made into "new" people.
1Sa 10:5
After that you shall come to Gibeath-elohim, where there is a garrison of the Philistines. And there, as soon as you come to the city, you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and lyre before them, prophesying.
