“Sanctification” vs “Conformation”

Considering the significance in the meaning of the above terms, I believe it would good to note the difference between them. Sanctification is a single work and is synonymous with holiness, which is to identify someone or something that belongs to God, which He has set apart for His pleasure. Conformation is an ongoing work of the forming of someone or something.

The potential misunderstanding when confusing the two is in how they are related to salvation. The occurrence of receiving salvation is a single act which does not admit in degrees, i.e. no believer is more or less saved than any other believer, and it has no variations in quality or quantity. One is either regenerated or not, which answers to why “sanctified” is always in the past tense in Scripture. Believers “are sanctified” because God has sanctified them at rebirth.

Conformation (not to confuse with confirmation) is the progressive work of God concerning the walk and faith of the believer, which are primarily purposed to manifest Himself through the believer. The most significant error that can be made if confusing these two terms is when conceiving that salvation (redemption) is an incomplete work within the believer, as though there are other factors besides the Cross-work of Christ to effect salvation.

All who are saved are sanctified, and this will inevitably be revealed in their manner of life as God continues to “conform” them, which “are change into the same image from glory to glory” (2Cor 3:18), “to the image of His Son (Rom 8:29).
