Sanctification as a continual process

There is a growth process in holiness in a Christian’s life. We have to remember that our model is Christ Himself. Thus the normal process of sanctification is a continual process.

(Philippians 3:12,13)
12 Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. 13 Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead.
