May the God of peace himself sanctify you completely. May your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.
Wholly - ὁλοτελεῖς holoteleis. In every part; completely. It is always proper to pray that God would make his people entirely holy. A prayer for perfect sanctification, however, should not be adduced as a proof that it is in fact attained in the present life.
