2 Corinthians 10:3-5 (NLT) "We are human, but we don’t wage war as humans do. We use God’s mighty weapons, not worldly weapons, to knock down the strongholds of human reasoning and to destroy false arguments. We destroy every proud obstacle that keeps people from knowing God. We capture their rebellious thoughts and teach them to obey Christ."
Many Christians don't realize that they are in a battle. We have an Enemy who opposes us in every way—his purpose is to prevent us from becoming who God wants us to be and achieving what He'd have us do. The Devil frustrates our plans, confuses our minds, and brings feelings of anxiety and despair. But he doesn't stop there; he also stirs up disunity in our relationships and churches.
There are several things that Christians should understand about this combat:
The battle is real, even if we can't see it. The difficulty, pain, and discouragement Satan causes are genuine. His temptations are not imaginary; they overwhelm and lure us away from the Lord.
The battle is spiritual. Our struggle is not with one another but with invisible forces of wickedness. Although the conflict is waged in the spiritual realm, it impacts every part of us—our mind, will, emotions, desires, and even our bodies.
The battle is tough. The Adversary fights dirty, and the encounter is "up close and personal." Our confrontation with the forces of evil is like spiritual hand-to-hand combat and flesh-to-flesh wrestling. He has a host of demonic beings who work unceasingly, even when we sleep. As long as we are on earth, the war will continue.
Although the Enemy is strong, there isn't reason to fear—he's no match for Christ, who lives within us. We've been entrusted with Jesus' divine power over the Evil One. However, we can access the Son's authority only by submitting to His lordship and walking in obedience to His Spirit.
