The examples of spiritual warfare are so various, multifarious and multifaceted that it is
impossible to list them one by one here. But I want to point out two typical examples of
spiritual warfare. One is the spiritual warfare within us Christians. This spiritual warfare is the inner struggle between our old Adam and our new Adam and between our sinful nature and our new creation. The apostle Paul talks about this inner spiritual warfare within us Christians in Romans 7:20-25. The spiritual warfare between good and evil is going on inside us Christians. The spiritual warfare between God’s law and the law of sin is continually taking place inside us Christians. The spiritual warfare between us and sin is ceaselessly going on inside us believers. The spiritual warfare between the law of sin and the law of our minds is waging inside us churchgoers. The spiritual warfare between our inner beings and the members of our bodies is violently waving within us the people of God. The law of sin is waging war against the law of our minds so that we become frequently a slave to the law of sin and a prisoner of the law of sin. Therefore, the Holy Spirit is often grieved by us, and our Lord Jesus Christ cannot have the opportunity to fight through us against the devil’s schemes.
The question is how we can become victorious in this inner and ongoing spiritual warfare. If we are defeated in this inner struggle, we cannot make any contribution to the expansion of the kingdom of God. So, Jesus teaches us to pray as follows: “Thy kingdom come and thy will be done on earth, as it is in heaven.” The apostle Paul point us to the way to becoming victorious in the inner spiritual warfare in Galatians 5:16-18, “So I say, live by the Holy Spirit, and you will not gratify the desires of the sinful nature. (17) For the sinful nature desires what is contrary to the Holy Spirit, and the Holy Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. (18) But if you are led by the Holy Spirit, you are not under law.”
