For this is the will of God, even your sanctification, Christ prayed earnestly to the Father for the Holy Spirit to be given to His people, which is synonymous with Sanctification. I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil. They are not of the world , even as I am not of the world. As thou hast sent me into the world, even so have I also sent them into the world. And for their sakes I sanctify myself, that they also might be sanctified through the truth.
Sanctification is a consecrating of the new life and a dying out to our self life.
Also, an eradication of our sinful nature is brought about by the infilling of Holy Spirit. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. In the religious institutions of men, they all speak a different language. Some say people need to be sprinkled when baptized and others submerged.
