Be ye therefore perfect, even as your Father which is in heaven is perfect. Matthew 5:48
(ML 271.1)
God will accept only those who are determined to aim high. He places every human agent under obligation to do his best. Moral perfection is required of all. Never should we lower the standard of righteousness in order to accommodate inherited and cultivated tendencies to wrongdoing. We need to understand that imperfection of character is sin. All righteous attributes of character dwell in God as a perfect, harmonious whole, and every one who receives Christ as a personal Saviour is privileged to possess these attributes.
(ML 271.2)
And those who would be workers together with God must strive for perfection of every organ of the body and quality of the mind. True education is the preparation of the physical, mental, and moral powers for the performance of every duty; it is the training of body, mind, and soul for divine service. This is the education that will endure unto eternal life....
(ML 271.3)
But Christ has given us no assurance that to attain perfection of character is an easy matter. A noble, all-around character is not inherited. It does not come to us by accident. A noble character is earned by individual effort through the merits and grace of Christ. God gives the talents, the powers of the mind; we form the character. It is formed by hard, stern battles with self. Conflict after conflict must be waged against hereditary tendencies. We shall have to criticize ourselves closely, and allow not one unfavorable trait to remain uncorrected.
(ML 271.4)
Let no one say, I cannot remedy my defects of character.... The real difficulty arises from the corruption of an unsanctified heart and an unwillingness to submit to the control of God.
(ML 271.5)
Subjection to the will of Christ means restoration to perfect manhood.
(ML 271.6)
