Yes, but what is repentance? It's not to be considered work in relation to salvation, for if it was, then it becomes something we do in order to earn or pay for salvation, but salvation is not earned or paid for, but freely given. Repentance comes from the conviction of God's Word - the Law, the letter that kills - and His work in us. It's the Holy Spirit that works in us, compelling us to turn to God. Repentance, faith and salvation is not to be attributed to ourselves, lest we should boast.
If we start thinking of salvation as a co-operative effort between God and us, we're going hard against what Scriptures say about God's grace and the Gospel (and this is Semipelagianism), for the Word explicitly say God's grace is free, and this is what the reformation was all about. Even the word "grace" comes from "gratis/gratus", which can mean "thankful, pleasing, free".
To my knowledge, the majority of Protestants today still teach imputed grace. Here we differ with our Catholic friends.

A lot can be said about this, but consider this - Our Lord Jesus Christ said we have to be born again. Who can choose to be born? How? By what means? For man to be born again is impossible, but it is possible for God. John 3:1-21
We have a Christian duty to bear good fruit according to God's Word, but this in no way or shape affect or compromise our salvation. Because then it becomes a question of "Did I truly repent of all my sins? Did I accept Jesus honestly enough? Did I do enough to earn my salvation?"
In a word, salvation is freely given and good works follows, as the fruit of the Spirit, and it has been prepared for us by God.
Ephesians 2:10 sums all of this very efficiently:
"For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
Notice here:
1. We are God's handiwork - Who made us? God created us.
2. Created in Christ - How are we in Christ? God created us in Christ - we didn't choose to be 'created', it's already decreed. God spoke and it is. God's Word does not return void.
3. Good works - Why are we created in Christ? In order that we may bear good fruits, by God, for God, through God.
4. Good works prepared - Where does good works come from? From God alone, the source and author of all good things. The good works we perform is at the mercy of God in that He freely gave it to us that we should walk in them through Christ.
The bottom line is that apart from Jesus, we can do nothing - certainly not work our own salvation through our own means, even in a co-operative effort. God alone saves.
