My family has served in the military since coming to this country. We served out of duty and honor and necessity. Everyone knows what a battleground is. It is not a place of preparation. The battleground is the execution of commands to preserve the integrity of the unit and to defeat the enemy. Sometimes the fighting is hand to hand, but most times it is long distance. Two of my sons served in war and still feel the effects from it. Waging war is a conscious effect on our part. We have to commit ourselves to the battle. When we choose to serve Christ, we choose to enter into battle. We do not fight against flesh and blood, but we battle against spiritual darkness. Since our enemy is invisible, we cannot see them with our eyes. But we can see them with our heart. And therein is the battleground. Our heart is our mind, will and intellect. Our mind is influenced by our five senses. They influence our body. As pressure comes against our body and mind is directly affected. If too much pressure comes against our body and mind will do one of two things. Our mind will fight against the pressure or oppression. Or our mind will give in and we lose ground. Which in turn affects our heart. And whosoever we serve, we become their servants. Whether or not, it is good or evil. This is why God commands us to think on things that are true, honest, just, pure, lovely and are of good report. This is how God keeps our minds and hearts through Christ Jesus. (Philippians 4:4-8).
