Paul says in 1Corinthians 1:31 that Christ is made unto us wisdom, justification, sanctification and redemption. The clear meaning of this is that we have no role to play in our sanctification any more than we do in our justification. It all comes from Christ.
In fact in Calvinism one does not even choose. So not even that role either.
We are not at all infinitely wise - yet Christ is "our wisdom" not just our Sanctification.
Justification involves the choice to accept the Gospel.
Sanctification looks like this according to Paul -
1 Cor 9:
23 I do all things for the sake of the gospel,
so that I may become a fellow partaker of it.
24 Do you not know that those who run in a race all run, but
only one receives the prize? Run in such a way that you may win. 25 Everyone who competes in the games exercises self-control in all things. So they
do it to obtain a perishable wreath,
but we an imperishable. 26 Therefore I run in such a way as not
to run aimlessly; I box in such a way, as to avoid hitting air; 27 but I strictly discipline my body and make it my slave, lest after I have
preached the gospel to others, I myself will not be disqualified. from it,
Phil 3:
7 But what things were gain to me, these I have counted loss for Christ. 8 Yet indeed I also count all things loss for the excellence of the knowledge of Christ Jesus my Lord, for whom I have suffered the loss of all things, and
count them as rubbish, that I may gain Christ 9 and be found in Him, not having my own righteousness, which
is from the law, but that which
is through faith in Christ, the righteousness which is from God by faith; 10 that I may know Him and the power of His resurrection, and the fellowship of His sufferings, being conformed to His death, 11
if, by any means, I may attain to the resurrection from the dead.
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, 14
I press toward the goal for the prize of the upward call of God in Christ Jesus.
