Eternal sin

Christian perfection
Wesley did not, however, believe in an absolute "sinless" perfection, and he repudiated those who taught that Christians could achieve such a state. Wesley defined sin as conscious, voluntary transgression of known divine law. Involuntary transgressions (such as those arising from ignorance, error, and evil tempers), according to Wesley, were not properly called sins. Therefore, regenerated Christians would continue to be guilty of involuntary transgressions and would need to practice regular confession. Furthermore, Christians continued to face temptation, and Wesley acknowledged that it was possible for a regenerated Christian to commit voluntary sin (if, in the words of Noble, the Christian ceased "actively trusting in God through Christ and living in the divine presence"), which would also necessitate confession of sin.
