[Dr. Eckleburg]

As I see it, part of repentance is the opportunity to learn. Since we will never run out of things to learn of God, it is a lifelong process.

Amen. Our repentance is life-long because our sanctification is life-long. But the ability to repent is given by God. Therefore it's not something we do in order to earn salvation because God's mercy is free and unmerited and dependent on Christ's work on the cross alone. However our repentance most assuredly will accompany our salvation.

"In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth" -- 2 Timothy 2:25

WESTMINSTER CONFESSION OF FAITH
Of Repentance Unto Life

III. Although repentance is not to be rested in, as any satisfaction for sin, or any cause of the pardon thereof, which is the act of God's free grace in Christ, yet it is of such necessity to all sinners, that none may expect pardon without it.

Amen. I thought the quote you gave from Westminster was perfect. :)
