When Goliath came against Israel and challenged them to a fight, the men of Isreal was afraid, and wouldn’t go against this giant. The reason why they were scared was because of how they saw themselves, in the face of their situation, you cannot march against an enemy that has defeated you already within your mind, the problem we are faced with today is this, our enemy which always presents himself through problems has a way of getting into our head, because this devil knows that if he can mess with our head, then he can have your peace and steal your joy. So the first thing that the Lord has to restore is your mind, where your thoughts live, now for you to have the mind of Christ, you have to feed your spirit with the word of God.
David’s mind was right, simply because he had the Spirit of the Lord living big inside of him, so when David heard about Goliath his answer was right, who is this uncircumcised Philistine that’s defying the army of the Lord. There was no fear of defeat in David’s mind, not because David had confidence in himself, David’s strength was in his God, and the name of the Lord. That’s how David defeated Goliath, some men trust in horses, some they trust in chariots but we will trust in the Name of our God, for the Bible says the people that know God shall be strong and do exploits.
The stone represents Christ the Word, five speaks of truth, whenever you come against the enemy you have to be armed with the word, and truth will always deliver you, and your enemies into your hands. But truth cannot help you if it’s not coming against the head of your enemy, the stone was directed to the head of Goliath.
