On self-sins

AW Tozer

   I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me.—Galatians 2:20

To be specific, the self-sins are self-righteousness, self-pity, self-confidence, self-sufficiency, self-admiration, self-love and a host of others like them. They dwell too deep within us and are too much a part of our natures to come to our attention till the light of God is focused upon them. The grosser manifestations of these sins—egotism, exhibitionism, self-promotion—are strangely tolerated in Christian leaders, even in circles of impeccable orthodoxy. They are so much in evidence as actually, for many people, to become identified with the gospel. I trust it is not a cynical observation to say that they appear these days to be a requisite for popularity in some sections of the church visible. Promoting self under the guise of promoting Christ is currently so common as to exite little notice....

Self is the opaque veil that hides the face of God from us. It can be removed only in spiritual experience, never by mere instruction. We may as well try to instruct leprosy out of our system. There must be a work of God in destruction before we are free. We must invite the cross to do its deadly work within us. We must bring our self-sins to the cross for judgment.  
(The Pursuit of God, 43-44)

AW Tozer on Spiritual Warfare

This from Bible Gateway  Spiritual Warfare and Sin: Irreconcilable Hostility For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.—Ephesians 6:12 In the early days, when Christianity exercised a dominant influence over American thinking, men and women conceived the world to be a battleground. Our fathers believed in sin and the devil and hell as constituting one force, and they believed in God and righteousness and heaven as the other. By their very nature, these forces were opposed to each other forever in deep, grave, irreconcilable hostility. Humans, our fathers held, had to choose sides-they could not be neutral. For them it must be life or death, heaven or hell, and if they chose to come out on God's side they could expect open war with God's enemies. The fight would be real and deadly and would last as long as life continued here below. People looked forward to heaven as a return from the wars, a laying down of the sword to enjoy in peace the home prepared for them.... How different today. The fact remains the same, but the interpretation has changed completely. People think of the world, not as a battleground, but as a playground. We are not here to fight; we are here to frolic. We are not in a foreign land; we are at home. We are not getting ready to live, but we are already living, and the best we can do is rid ourselves of our inhibitions and our frustrations and live this life to the full. This World: Playground or Battleground?, 4-5. "Lord, we've lost too much by becoming friendly with the enemy. Help me to be willing to take a stand for righteousness, to choose clearly to be on Your side against the enemy, to pay any price—and then to look forward to laying down my sword later in heaven. Amen."

AW Tozer on Leadership

Spiritual Warfare and Sin: Eternal Enmity Beloved, do not think it strange concerning the fiery trial which is to try you, as though some strange thing happened to you; but rejoice to the extent that you partake of Christ's sufferings, that when His glory is revealed, you may also be glad with exceeding joy.—1 Peter 4:12-13 There are two spirits in the earth, the Spirit of God and the spirit of Satan, and these are at eternal enmity. The ostensible cause of religious hatred may be almost anything; the true cause is nearly always the same: the ancient animosity which Satan, since the time of his inglorious fall, has ever felt toward God and His kingdom. Satan is aflame with desire for unlimited dominion over the human family; and whenever that evil ambition is challenged by the Spirit of God, he invariably retaliates with savage fury.... It is possible within the provisions of redemptive grace to enter into a state of union with Christ so perfect that the world will instinctively react toward us exactly as it did toward Him in the days of His flesh.... It is the Spirit of Christ in us that will draw Satan's fire. The people of the world will not much care what we believe and they will stare vacantly at our religious forms, but there is one thing they will never forgive us-the presence of God's Spirit in our hearts. They may not know the cause of that strange feeling of antagonism which rises within them, but it will be nonetheless real and dangerous. Satan will never cease to make war on the Man-child, and the soul in which dwells the Spirit of Christ will continue to be the target for his attacks. The Warfare of the Spirit, 3-4. "Lord, thank You for victory through Jesus Christ. Amen."
