“For this is the will of God, [even] your sanctification, that ye should abstain from fornication: That every one of you should know how to possess his vessel in sanctification and honour” 1Thessalonians 4:3-4

“The Scriptures plainly show that the work of sanctification is progressive. When in conversion the sinner finds peace with God through the blood of the atonement, the Christian life has but just begun. ” Great Controversy 470.1

“The steps requisite in conversion are repentance, faith and baptism. And then after these steps are taken, the life of prayer is essential to maintain the Christian life, and to seek those things which are above where Christ sitteth, you cannot stop at baptism and feel that you have graduated. Your Christian life is only entered upon, the formation of Christian character is yet before you, you have just entered the school of Christ, and need to continue to learn of him. You are to continue to be instructed in the school of Christ, having the heart open to receive the heavenly knowledge that will be imparted unto you; and thus you will grow in grace and the knowledge of the truth.”  The Signs of the Times, February 14, 1878 par. 5, 6

“Let no one suppose that conversion is the beginning and end of the Christian life… There is to be growth in grace that is constant progress and improvement. The mind is to be disciplined, trained, educated; for the child of God is to do service for God in ways that are not natural, or in harmony with inborn inclination. Those who become the followers of Christ find that new motives of action are supplied, new thoughts arise, and new actions must result.” Christian education 122.1
