Sanctification is an act of separation from that which is evil, and of dedication unto God.
The Scriptures teach a life of "holiness without which no man shall see the Lord."
By the power of the Holy Ghost we are able to obey the command: "Be ye holy, for I am holy."
Sanctification is realised in the believer by recognising his identification with Christ in His death and resurrection, and by the faith reckoning daily upon the fact of that union, and by offering every faculty continually to the dominion of the Holy Spirit.
