The gospel of the kingdom of heaven is aimed particularly toward the power of darkness. When the Lord Jesus first preached the gospel of the kingdom of heaven, all His works were aimed at dealing with the power of darkness. "The Son of God was manifested, that He might destroy the works of the devil" (1 John 3:8). He healed the sick and cast out the demons. The casting out of the demons is surely an annulling of the power of darkness. But what about healing the sick? The apostle gave us a footnote to healing: "Healing all those who were being oppressed by the devil" (Acts 10:38). If we study the Gospels carefully, we will see that throughout His life, the Lord Jesus was destroying the work of the devil. Hence, His work in this world produced more effect on the demons than on men.
The Lord Jesus said that at the end time, some of His children will rise up to bear this testimony. We thank the Lord that during the past few years, quite a number of God's children have risen up to wage war against Satan. Spiritual warfare is no longer just a term; it has become a reality that is experienced by many believers. Truly we are at the end of this age.
