By this faith, a Christian believes to be true whatsoever is revealed in the Word, for the authority of God Himself speaking therein; and acts differently upon that which each particular passage thereof contains; yielding obedience to the commands, trembling at the threatenings, and embracing the promises of God for this life, and that which is to come. But the principal acts of saving faith are accepting, receiving, and resting upon Christ alone for justification, sanctification, and eternal life, by virtue of the covenant of grace.
WCF XIV.2
By this faith, a Christian believes to be true whatsoever is revealed in the Word, for the authority of God Himself speaking therein; and acts differently upon that which each particular passage thereof contains; yielding obedience to the commands, trembling at the threatenings, and embracing the promises of God for this life, and that which is to come. But the principal acts of saving faith are accepting, receiving, and resting upon Christ alone for justification, sanctification, and eternal life, by virtue of the covenant of grace.
Saving faith receives and rests upon Christ for sanctification as well as justification. So, yes. The faith that is a gift of God receives Christ entire and undivided, and sanctification is as much a part of the salvation Christ acquired as justification.
Principal means "first in order of importance" not "first in order of sequence".
Accepting, receiving, and resting on Christ are the primary or cardinal acts of saving faith; your own self-awareness in performing those acts is not essential to the being of the act. Subsequent reflection will often unpack the fullness of what was involved in an act that seemed at the time to be pure simplicity.
Can we say the faith that justifies is the same faith that sanctifies?
We are saved by faith (justified, sanctified... the whole ball o' wax) and we also live the Christian life by faith (as the sanctification part continues to happen).
Phrasing it the other way might suggest the idea that initial salvation includes only justification and sanctification is something that comes later. Well, although sanctification is indeed ongoing, it is really just a continuation of what happened initially. At our conversion we began a life of faith, and we never give that up.
