I don't know how you deduce sinless out of the need for repentance. Not all sin is transgression. Not all sinfulness is rebellion.
KJV Numbers 15:29 Ye shall have one law for him that sinneth through ignorance, both for him that is born among the children of Israel, and for the stranger that sojourneth among them. 30 But the soul that doeth ought presumptuously, whether he be born in the land, or a stranger, the same reproacheth the LORD; and that soul shall be cut off from among his people.
God changes the heart to turn us to him, ....
God will not do that if the person is unwilling to cooperate:
KJV Deuteronomy 10:16 Circumcise therefore the foreskin of your heart, and be no more stiffnecked.
KJV Deuteronomy 30:6 And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
I absolutely disagree. ALL sin is rebellion. Sin is death. God will not do that if the person is unwilling to cooperate:
God is sovereign. His will is sovereign. He will do what He wills. If you don't recognize this, you believe in a different God than I do. You also believe a different gospel that is not of Christ. I don't know if your heart has been circumcised only God sees your heart, I pray that it is.
