We believe God has been giving dreams and visions to people since the beginning of time and is still using them to reveal things to His people. Rick Joyner is an established and verified prophetic voice, The Harvest and Final Quest series are must reads. They will cast out any doubt of his legitimacy. I personally heard 10 years ago by an intelligence personnel that Islamic terrorists were using our porous border to flood into the country to prepare for attacking us from within. Numerous intel, eye witness, military, and prophetic/watchman sources have confirmed this over the years (see John Paul Jackson and Steve Quayle) independently of one another. Take a few minutes and look at all the news reports if you doubt Islamic terror is already in our country, waiting for the command to strike. As always, take everything to the Lord in prayer and weigh it with scripture.
Hosea 4:6 My people are destroyed for lack of knowledge.
1 John 4:18 There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love.
