We are in a war. Not only a war, but a dirty war because the devil fights dirty. He is dirty because he is deceptive. If he would come straight at us, most of us would not have a problem dealing with his assault, but he rarely comes that way. That is why, the bible tells us to put on the full armor of all that God gives us to protect us from the assault. Paul writes to a church that was under assault. He reminds them of how the devil operates with his various devices. In the Greek, the word devices means strategy. Paul deals with a church that was liberal in their interpretation of the gospel. They embraced another gospel other than the one true gospel. Paul said that he was fearful that they did not see what was happening. Paul used the terminology of weddings of the time to illustrate his position. He reminded the church at Corinth that faithfulness was essential to the relationship with God. The only way to build a true relationship is to have faithfulness between the two parties. Paul was fearful that they were being led astray as Satan led Eve astray. We are dealing with a deceitful and cunning foe. He will come at us in a way that will be attractive and compelling. He will use what ever he can use to gain an advantage.
Paul tells us that it is Satan's goal to move us from the simplicity that is in Christ. Christ was not simple, but our relationship with Him is. The simplicity of a relationship with Christ stands in contrast with the duplicity and complexity of a relationship with Satan. When we have complexity, we have things moving in different directions. The devil wants to complicate life to the point where we cannot focus on the simplicity of the relationship with Christ. If the devil cannot make us bad, he will make us busy. Paul describes a life that is all on one side of the page. If the page becomes folded, part of life is going a different way. Some of life is hidden. This is just what the devil wants. He wants to disrupt the flow of life by adding burden and distractions. That way we will lose sight of our true priorities.
