When the heart is cleansed from sin, Christ is placed on the throne (our mind) that self-indulgence and love of earthly treasure once occupied. The image of Christ is seen in the expression of the countenance. The work of sanctification is carried forward in the soul. Self-righteousness is banished. There is seen the putting on of the new man, which after Christ is created in righteousness and true holiness."—The Review and Herald, September 11, 1900.Counsels on Stewardship, p. 27.

cleansing = Christ in the heart Eph 3:17  That Christ may dwell in your hearts by faith. This is clearly showing how to be sinfree if we have a correct understanding of faith.

Another intresting point is the putting on of the new man. Indeed this is sinfreeness also called the new birth or regeneration. Titus 3:5-7 KJV

11 Now the parable is this: The seed is the word of God" Luke 8:11 (KJV).

Rev 19:13 "And he was clothed with a vesture dipped in blood: and his name is called The Word of God"
