Why, if Jesus triumphed over Satan, is there still sin in the world?
It is possible that a sentence may be pronounced and made known some time before the sentence is actually executed. During this interval a criminal is said to be under sentence awaiting his execution which some higher authority has decreed. This period of sentence is that in which Satan appears in the present age, which had its beginning with the cross. Execution of this sentence would have banished him forever. That he has not been banished is revealed in the fact that he, even after his judgment, is referred to in the Scriptures as still being in authority over this world.
The real church, which is the bride of Christ, is to sit with Him upon His throne (Rev. 3:21; 1 Corinthians 6:2,3; Matt. 19:28), and the present age must continue until that glorious heavenly people are gathered out from the world. When all is said and done, those who refused God’s commands will stand self-condemned, and nothing can accomplish this but the testing, by trial, of all the self-sufficient claims of Satan and man. The sin of man has brought him under sentence too, and grace alone withholds his immediate execution (John 3:18; Romans 5:18,19). Though the day of execution is, by God’s will, delayed, it is certain; and the time is fast approaching when the complete destruction of all self-enthroned beings will be executed, and Christ alone will reign, “for He must reign until He has put all His enemies under His feet” (1 Corin. 15:25). The kingly Son of God will arise and claim the nations of the earth and “break them with a rod of iron; and dash them in pieces like a potter’s vessel” (Psalm 2:9).
Another reason for the delay in the termination of evil from the world and the execution of judgment upon Satan is that the presence of evil in the world provides the Christian with a ceaseless conflict by which he or she can develop the character to overcome. This type of victorious characteristic in the believer is priceless in God’s sight.
Satan is thus revealed in Scripture as having been created perfect in his ways, mighty in power, and full of beauty and wisdom. While blessed in this way, he proposed in his heart to make himself like God. Though remaining in heaven and having access to God, he (having taken the scepter of authority from Adam through Adam’s disobedience to God) is the ruling god of this world until God chooses to execute His sentence against Satan and his followers. In the middle of the tribulation Satan will be cast out of heaven onto the earth, with further access to heaven denied. From there he will be sent to the abyss during Christ’s reign in the Millennium and, after a short time of release, he and all who have ever followed him will be banished to the lake of fire (hell) forever.
Can anyone then doubt that this mighty being called Satan is a living power acting directly over the affairs of men in this self-glorifying age?
