In the Old Testament the cities had walls around them with huge gates that could be closed at night for protection. They also had a watchtower on the wall so someone could stand guard at all times and be able to see, from his vantage point, what others in the city could not see. If they saw a known enemy approaching they would sound an alarm so the armies could get into battle mode!! There are chosen ones in the earth that God talks to and they talk to God therefore letting them see what others cannot see. They are Prophets, they feel what others do not feel, they know what others do not know and they hear the plans of God before others are ever aware of what's going on in their world.
"Surely the Lord God will do nothing, but he revealeth his secret unto his servants the prophets." (Amos 3:7 KJV)
This anointing from God will bring protection to the people that listen to these inspired Preachers because their understanding of the times is "ahead of the curve"! Samuel the Prophet anointed David when he was a teenager and he single handedly killed the giant Philistine named Goliath. (1 Samuel 16:13) This victory by an anointed teenager outraged the Philistines and when David was anointed King over all Israel, all the Philistines came against David but he defeated them by the power of listening to God's Voice!!
"David, Go up: for I will doubtless deliver the Philistines into thine hand. And David came to Baal–perazim, and David smote them there, and said, The Lord hath broken forth upon mine enemies before me, as the breach of waters." (2 Samuel 5:19-20 KJV)
Samuel the Prophet had sought David out and layed his hands on him thereby setting him apart with supernatural power, perception and prosperity!
"So the Philistines were subdued, and they came no more into the coast of Israel: and the hand of the Lord was against the Philistines all the days of Samuel." (1 Samuel 7:13 KJV)
Samuel the Prophet was basically a "Spiritual Watchtower" moving as moved by The Lord which brought protection to Israel. It's not hard to tell if a Preacher is a Prophet, he will see things differently, he will approach things differently and you will feel different when in his presence. You would do well to listen when he speaks..... ( Prophet-inspired speaker that is activated by the Spirit of God and not moved by anything other than the Voice of God)
