Who said ANYTHING about self-improvement? A Christian has repented have they not, or do you think the Holy Spirit repents for them?

According to your reference text, repentance unto the knowledge of the truth is a gift of God not a work of man.

Think about it for a moment, if you are not repenting and acknowledging the truth of God then you are not in true communion with God. I repent continually and am able to acknowledge God's truth as I am a recipient of His grace.

Why am I repenting and acknowledging the truth of God? Why am I able to acknowledge God's truth? If repentance is a gift of God, it cannot be a good work. The definition of good work is something that a child of God does in faith. I am kept in repentance by the Holy Spirit (1 Peter 1:5; Phil. 1:6; 1 Thes. 2:13; Titus 3:5) and enlightened by His gifts (2 Cor. 4:6; Rom 15:13; 1 Peter 2:9).

The Holy Spirit gives me assurance of salvation not my good works.
