What is the strength of a warrior? Is it his physical strength? Is it his fighting ability? Is it his endurance? These are all great assets that a warrior must possess, but these are not the strength of a warrior. The strength of a warrior is his heart.
This is what makes a man strong and to continue to fight when he physically can’t go any further. We were created by God and He placed at the center of man the heart. The heart is the life beat of the human body. If it stops, we would die. It is the same in the spiritual as in the natural. The heart is the center of our spiritual being and we must keep it free from pollutants because they, like in the physical make the heart weak, damage the heart and even make it stop.
We have many people walking around spiritually dead with no life in their heart because they have not looked to the source of strength. This is why there is a battle for control over the heart. Satan knows that if he can capture your heart, he can capture your strength. He will attack your heart from any angle; circumstance, jealousy, expectation or pride. You must have a strong heart to defeat your enemies.
