1. Selfishness as the Root of All Evil

"Selfishness is the root of all evil, and it leads to discontent, strife, and every other sin. It blinds the soul to the needs of others and leads the individual to live for self, rather than for God and others."
— Christ's Object Lessons, p. 67

2. Christ’s Example of Selflessness

"Christ's life was one of complete unselfishness, and this is the standard that every Christian must strive for. He lived for others, and His work was to do the will of His Father. Selfishness and self-centeredness are the very opposite of the life that Christ lived."
— The Desire of Ages, p. 301

3. Selfishness and Spiritual Decline

"Selfishness is an offense against God. It is the cause of discontent, of discord, and it will separate us from God if we allow it to rule our hearts. The more selfishness there is in our lives, the further we are from true Christian experience."
— The Ministry of Healing, p. 500

4. The Call to Self-Denial and Service

"The path of self-denial and self-sacrifice is the path that leads to true joy and fulfillment. Christ calls us to forsake self-centeredness and live a life of service to others. In doing so, we find true peace and satisfaction."
— Steps to Christ, p. 70

5. Selfishness in Relationships

"Selfishness is the root of all conflicts in the home and in the church. Where selfishness reigns, love is absent. True love in the home is unselfish, and it seeks the welfare of the other person before its own."
— The Adventist Home, p. 220

6. The Dangers of Selfishness in Christian Ministry

"In Christian ministry, it is easy for the servant of God to become selfish and seek his own honor. But God has called us to a life of service, not to be served. Ministers and workers in the church must guard against the temptation to seek their own advancement, and must humbly serve, looking to Christ as their example."
— Testimonies for the Church, vol. 3, p. 532

7. Selfishness and the Gospel Call

"The gospel of Christ is the message of self-denial. Those who truly accept Christ's sacrifice are called to live for others, to reflect the character of Christ in every action. When we die to self, we begin to truly live for God and for the good of humanity."
— Desire of Ages, p. 301

These quotes encapsulate Ellen G. White’s teaching on selfishness, emphasizing its destructive power and the call to live a life of selflessness in imitation of Christ.
